The pain is usually associated with ERYTHEMA; SKIN TEMPERATURE changes, abnormal sudomotor activity (i.e., changes in sweating due to altered sympathetic innervation) or edema. The degree of pain and other manifestations is out of proportion to that expected from the inciting event. Two subtypes of this condition have been described: type I; (REFLEX SYMPATHETIC DYSTROPHY) and type II; (CAUSALGIA). (From Pain 1995 Oct;63(1):127-33)Goldenhar Syndrome: Mandibulofacial dysostosis with congenital eyelid dermoids.Carrier Proteins: Transport proteins that carry specific substances in the blood or across cell membranes.Respiratory Distress Syndrome, Newborn: A condition of the newborn marked by DYSPNEA with CYANOSIS, heralded by such prodromal signs as dilatation of the alae nasi, expiratory grunt, and retraction of the suprasternal notch or costal margins, mostly frequently occurring in premature infants, children of diabetic mothers, and infants delivered by cesarean section, and sometimes with no apparent predisposing cause.Neuroleptic Malignant Syndrome: A potentially fatal syndrome associated primarily with the use of neuroleptic agents (see ANTIPSYCHOTIC AGENTS) which are in turn associated with dopaminergic receptor blockade (see RECEPTORS, DOPAMINE) in the BASAL GANGLIA and HYPOTHALAMUS, and sympathetic dysregulation.

Some specific groups are NONOXYNOLS, OCTOXYNOLS, and POLOXAMERS.Neoplastic Syndromes, Hereditary: The condition of a pattern of malignancies within a family, but not every individual's necessarily having the same neoplasm. Characteristically the tumor tends to occur at an earlier than average age, individuals may have more than one primary tumor, the tumors may be multicentric, usually more than 25 percent of the individuals in direct lineal descent from the proband are affected, and the cancer predisposition in these families behaves as an autosomal dominant trait with about 60 percent penetrance.Fatal Outcome: Death resulting from the presence of a disease in an individual, as shown by a single case report or a limited number of patients. This should be differentiated from DEATH, the physiological cessation of life and from MORTALITY, an epidemiological or statistical concept.Thoracic Outlet Syndrome: A neurovascular syndrome associated with compression of the BRACHIAL PLEXUS; SUBCLAVIAN ARTERY; and SUBCLAVIAN VEIN at the superior thoracic outlet. This may result from a variety of anomalies such as a CERVICAL RIB, anomalous fascial bands, and abnormalities of the origin or insertion of the anterior or medial scalene muscles. Clinical features may include pain in the shoulder and neck region which radiates into the arm, PARESIS or PARALYSIS of brachial plexus innervated muscles, PARESTHESIA, loss of sensation, reduction of arterial pulses in the affected extremity, ISCHEMIA, and EDEMA. (Adams et al., Principles of Neurology, 6th ed, pp214-5).Hermanski-Pudlak Syndrome: Syndrome characterized by the triad of oculocutaneous albinism (ALBINISM, OCULOCUTANEOUS); PLATELET STORAGE POOL DEFICIENCY; and lysosomal accumulation of ceroid lipofuscin.Retrospective Studies: Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past.

Features of LEOPARD syndrome overlap with those of NEUROFIBROMATOSIS 1 which is caused by mutations in the NEUROFIBROMATOSIS 1 GENES.Hand Deformities, Congenital: Alterations or deviations from normal shape or size which result in a disfigurement of the hand occurring at or before birth.Protein Structure, Tertiary: The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.Eye Abnormalities: Congenital absence of or defects in structures of the eye; may also be hereditary.Li-Fraumeni Syndrome: Rare autosomal dominant syndrome characterized by mesenchymal and epithelial neoplasms at multiple sites. MUTATION of the p53 tumor suppressor gene, a component of the DNA DAMAGE response pathway, apparently predisposes family members who inherit it to develop certain cancers. The spectrum of cancers in the syndrome was shown to include, in addition to BREAST CANCER and soft tissue sarcomas (SARCOMA); BRAIN TUMORS; OSTEOSARCOMA; LEUKEMIA; and ADRENOCORTICAL CARCINOMA.Hamartoma Syndrome, Multiple: A hereditary disease characterized by multiple ectodermal, mesodermal, and endodermal nevoid and neoplastic anomalies. Facial trichilemmomas and papillomatous papules of the oral mucosa are the most characteristic lesions. Individuals with this syndrome have a high risk of BREAST CANCER; THYROID CANCER; and ENDOMETRIAL CANCER. This syndrome is associated with mutations in the gene for PTEN PHOSPHATASE.Asperger Syndrome: A disorder beginning in childhood whose essential features are persistent impairment in reciprocal social communication and social interaction, and restricted, repetitive patterns of behavior, interests, or activities. These symptoms may limit or impair everyday functioning. (From DSM-5)Mobius Syndrome: A syndrome of congenital facial paralysis, frequently associated with abducens palsy and other congenital abnormalities including lingual palsy, clubfeet, brachial disorders, cognitive deficits, and pectoral muscle defects. Pathologic findings are variable and include brain stem nuclear aplasia, facial nerve aplasia, and facial muscle aplasia, consistent with a multifactorial etiology. (Adams et al., Principles of Neurology, 6th ed, p1020)Fluorescence: The property of emitting radiation while being irradiated. The radiation emitted is usually of longer wavelength than that incident or absorbed, e.g., a substance can be irradiated with invisible radiation and emit visible light. X-ray fluorescence is used in diagnosis.Mice, Knockout: Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.Biological Markers: Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, environmental exposure and its effects, disease diagnosis, metabolic processes, substance abuse, pregnancy, cell line development, epidemiologic studies, etc.Receptors, Glucocorticoid: Cytoplasmic proteins that specifically bind glucocorticoids and mediate their cellular effects. The glucocorticoid receptor-glucocorticoid complex acts in the nucleus to induce transcription of DNA. Glucocorticoids were named for their actions on blood glucose concentration, but they have equally important effects on protein and fat metabolism. Cortisol is the most important example.Hepatorenal Syndrome: Functional KIDNEY FAILURE in patients with liver disease, usually LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL), and in the absence of intrinsic renal disease or kidney abnormality. It is characterized by intense renal vasculature constriction, reduced renal blood flow, OLIGURIA, and sodium retention.Waardenburg Syndrome: Rare, autosomal dominant disease with variable penetrance and several known clinical types. Characteristics may include depigmentation of the hair and skin, congenital deafness, heterochromia iridis, medial eyebrow hyperplasia, hypertrophy of the nasal root, and especially dystopia canthorum. The underlying cause may be defective development of the neural crest (neurocristopathy). Waardenburg's syndrome may be closely related to piebaldism. Klein-Waardenburg Syndrome refers to a disorder that also includes upper limb abnormalities.Systemic Inflammatory Response Syndrome: A systemic inflammatory response to a variety of clinical insults, characterized by two or more of the following conditions: (1) fever >38 degrees C or HYPOTHERMIA 90 beat/minute; (3) tachypnea >24 breaths/minute; (4) LEUKOCYTOSIS >12,000 cells/cubic mm or 10% immature forms. While usually related to infection, SIRS can also be associated with noninfectious insults such as TRAUMA; BURNS; or PANCREATITIS. If infection is involved, a patient with SIRS is said to have SEPSIS.Mutation, Missense: A mutation in which a codon is mutated to one directing the incorporation of a different amino acid. This substitution may result in an inactive or unstable product. (From A Dictionary of Genetics, King & Stansfield, 5th ed)Sleep Apnea Syndromes: Disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. Sleep apnea syndromes are divided into central (see SLEEP APNEA, CENTRAL), obstructive (see SLEEP APNEA, OBSTRUCTIVE), and mixed central-obstructive types.Prevalence: The total number of cases of a given disease in a specified population at a designated time. It is differentiated from INCIDENCE, which refers to the number of new cases in the population at a given time.Receptors, Estradiol: Cytoplasmic proteins that bind estradiol, migrate to the nucleus, and regulate DNA transcription.Cinanserin: A serotonin antagonist with limited antihistaminic, anticholinergic, and immunosuppressive activity.Binding Sites: The parts of a macromolecule that directly participate in its specific combination with another molecule.Adie Syndrome: A syndrome characterized by a TONIC PUPIL that occurs in combination with decreased lower extremity reflexes. The affected pupil will respond more briskly to accommodation than to light (light-near dissociation) and is supersensitive to dilute pilocarpine eye drops, which induce pupillary constriction. Pathologic features include degeneration of the ciliary ganglion and postganglionic parasympathetic fibers that innervate the pupillary constrictor muscle. (From Adams et al., Principles of Neurology, 6th ed, p279)Follow-Up Studies: Studies in which individuals or populations are followed to assess the outcome of exposures, procedures, or effects of a characteristic, e.g., occurrence of disease.Polyradiculoneuropathy: Diseases characterized by injury or dysfunction involving multiple peripheral nerves and nerve roots. The process may primarily affect myelin or nerve axons. Two of the more common demyelinating forms are acute inflammatory polyradiculopathy (GUILLAIN-BARRE SYNDROME) and POLYRADICULONEUROPATHY, CHRONIC INFLAMMATORY DEMYELINATING. Polyradiculoneuritis refers to inflammation of multiple peripheral nerves and spinal nerve roots.Prospective Studies: Observation of a population for a sufficient number of persons over a sufficient number of years to generate incidence or mortality rates subsequent to the selection of the study group.Ovarian Hyperstimulation Syndrome: A complication of OVULATION INDUCTION in infertility treatment. It is graded by the severity of symptoms which include OVARY enlargement, multiple OVARIAN FOLLICLES; OVARIAN CYSTS; ASCITES; and generalized EDEMA. The full-blown syndrome may lead to RENAL FAILURE, respiratory distress, and even DEATH. Increased capillary permeability is caused by the vasoactive substances, such as VASCULAR ENDOTHELIAL GROWTH FACTORS, secreted by the overly-stimulated OVARIES.Premenstrual Syndrome: A combination of distressing physical, psychologic, or behavioral changes that occur during the luteal phase of the menstrual cycle. Symptoms of PMS are diverse (such as pain, water-retention, anxiety, cravings, and depression) and they diminish markedly 2 or 3 days after the initiation of menses.Miller Fisher Syndrome: A variant of the GUILLAIN-BARRE SYNDROME characterized by the acute onset of oculomotor dysfunction, ataxia, and loss of deep tendon reflexes with relative sparing of strength in the extremities and trunk. The ataxia is produced by peripheral sensory nerve dysfunction and not by cerebellar injury. Facial weakness and sensory loss may also occur. The process is mediated by autoantibodies directed against a component of myelin found in peripheral nerves. (Adams et al., Principles of Neurology, 6th ed, p1313; Neurology 1987 Sep;37(9):1493-8)Capillary Leak Syndrome: A condition characterized by recurring episodes of fluid leaking from capillaries into extra-vascular compartments causing hematocrit to rise precipitously. If not treated, generalized vascular leak can lead to generalized EDEMA; SHOCK; cardiovascular collapse; and MULTIPLE ORGAN FAILURE.Korsakoff Syndrome: An acquired cognitive disorder characterized by inattentiveness and the inability to form short term memories. This disorder is frequently associated with chronic ALCOHOLISM; but it may also result from dietary deficiencies; CRANIOCEREBRAL TRAUMA; NEOPLASMS; CEREBROVASCULAR DISORDERS; ENCEPHALITIS; EPILEPSY; and other conditions. (Adams et al., Principles of Neurology, 6th ed, p1139)Neurocutaneous Syndromes: A group of disorders characterized by ectodermal-based malformations and neoplastic growths in the skin, nervous system, and other organs.Swine: Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail.

For disease models in living animals, DISEASE MODELS, ANIMAL is available. Biological models include the use of mathematical equations, computers, and other electronic equipment.Gitelman Syndrome: An inherited renal disorder characterized by defective NaCl reabsorption in the convoluted DISTAL KIDNEY TUBULE leading to HYPOKALEMIA. In contrast with BARTTER SYNDROME, Gitelman syndrome includes hypomagnesemia and normocalcemic hypocalciuria, and is caused by mutations in the thiazide-sensitive SODIUM-POTASSIUM-CHLORIDE SYMPORTERS.Microfilament Proteins: Monomeric subunits of primarily globular ACTIN and found in the cytoplasmic matrix of almost all cells. They are often associated with microtubules and may play a role in cytoskeletal function and/or mediate movement of the cell or the organelles within the cell.Recombinant Proteins: Proteins prepared by recombinant DNA technology.Wolfram Syndrome: A hereditary condition characterized by multiple symptoms including those of DIABETES INSIPIDUS; DIABETES MELLITUS; OPTIC ATROPHY; and DEAFNESS. This syndrome is also known as DIDMOAD (first letter of each word) and is usually associated with VASOPRESSIN deficiency. It is caused by mutations in gene WFS1 encoding wolframin, a 100-kDa transmembrane protein.Cells, Cultured: Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.Acquired Hyperostosis Syndrome: Syndrome consisting of SYNOVITIS; ACNE CONGLOBATA; PALMOPLANTAR PUSTULOSIS; HYPEROSTOSIS; and OSTEITIS. The most common site of the disease is the upper anterior chest wall, characterized by predominantly osteosclerotic lesions, hyperostosis, and arthritis of the adjacent joints. The association of sterile inflammatory bone lesions and neutrophilic skin eruptions is indicative of this syndrome.CREST Syndrome: A mild form of LIMITED SCLERODERMA, a multi-system disorder. Its features include symptoms of CALCINOSIS; RAYNAUD DISEASE; ESOPHAGEAL MOTILITY DISORDERS; sclerodactyly, and TELANGIECTASIS. When the defect in esophageal function is not prominent, it is known as CRST syndrome.Wasting Syndrome: A condition of involuntary weight loss of greater then 10% of baseline body weight. It is characterized by atrophy of muscles and depletion of lean body mass. Wasting is a sign of MALNUTRITION as a result of inadequate dietary intake, malabsorption, or hypermetabolism.Superior Vena Cava Syndrome: A condition that occurs when the obstruction of the thin-walled SUPERIOR VENA CAVA interrupts blood flow from the head, upper extremities, and thorax to the RIGHT ATRIUM. Obstruction can be caused by NEOPLASMS; THROMBOSIS; ANEURYSM; or external compression. The syndrome is characterized by swelling and/or CYANOSIS of the face, neck, and upper arms.SARS Virus: A species of CORONAVIRUS causing atypical respiratory disease (SEVERE ACUTE RESPIRATORY SYNDROME) in humans.

The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.Chemical Phenomena: The composition, conformation, and properties of atoms and molecules, and their reaction and interaction processes.Myasthenic Syndromes, Congenital: A heterogeneous group of disorders characterized by a congenital defect in neuromuscular transmission at the NEUROMUSCULAR JUNCTION. This includes presynaptic, synaptic, and postsynaptic disorders (that are not of autoimmune origin).

Sinoatrial block. Autonomic influences and clinical assessment. (1/27)

Seventeen patient with sinoatrial block and 16 healthy volunteers were investigated with recently developed autonomic tests of atrial pacemaker function. Only one patients was found to be entirely normal in comparison with normal subjects, while another patients had supernormal responses. Fifteen patients had reduced responses relative to the controls implying impaired atrial pacemaker function or sinoatrial disease. It is suggested that while in some cases sinoatrial block may be of physiological origin, it is more often due to sinoatrial disease. The latter group are liable to Adams-Stokes syncope and may have additional atricventricular conduction abnormalities. The possible mechanisms and treatment of sinoatrial block are discussed relative to the autonomic and pacemaker function abnormalities described.  (+info)

Electron microscopical study of myocardial biopsy material in congenital heart block. (2/27)

Myocardial tissue from the left ventricle of two children with congenital atrioventricular block and recurrent Admas-Stokes attacks was obtained during the procedure of epicardial pacemaker implantation and studied with the electron microscope. One patient had a familial cardiomyopathy, the other had no clinical abnormality apart from the conduction defect. Proliferation of mitochondria was common in both cases. Focal interstitial fibrosis and pronounced proliferation of transverse tubules were found in the myocardial cells of the patient with familial cardiomyopathy. Deep invaginations of the sarcolemmma with formation of intracytoplasmic channels were present in the second case. The possibility that the numerous transverse tubules could serve as additional pathways for impulse conduction is discussed.  (+info)

Advanced heart block aggravated by carbamazepine. (3/27)

This report presents a serious adverse reaction to the anticonvulsant compound carbamazepine. A woman was admitted to hospital for recurrent attacks of syncope. She suffered from atrioventricular block of the Mobitz type II. Carbamazepine suppressed the conduction in her already defective Purkinje fibres and induced ventricular stand-still with subsequent Adams-Stokes attacks.  (+info)

Complete heart block. Studies of atrial and ventricular pacemaker site and function. (4/27)

Atrial and ventricular pacemaker function was studied in 20 patients with idiopathic chronic complete heart block using the rate response to an intravenous bolus dose of isoprenaline (5 mug/70 kg bodyweight). Pacemaker responses were compared with those of 16 normal control subjects. None of the patients was having syncopal attacks at the time of admission and they were therefore selected in that none required immediate pacing. Ten of the patients had His bundle electrograms; all were shown to have a pre-His type of atrioventricular block. Two major groups emerge from the responses to isoprenaline. (a) High risk group: 11 of the 14 patients with reduced ventricular pacemaker responses had frequent syncopal attacks; 8 of the patients with Adams-Stokes syncope had a bundle-branch block pattern, while 3 had a narrow QRS. These patients require pacing. (b) Low risk group: a low risk asymptomatic group (5 patients) was identified with atrial and ventricular responses to isoprenaline within normal range. One of these patients had a bundle-branch block pattern, while 4 had a narrow QRS. These patients might be managed without pacing. The atrial response to isoprenaline was reduced in 12 of the 20 cases, 10 of whom also had reduced ventricular responses. All 9 patients with bundle-branch block had reduced ventricular responses, while 7 had reduced atrial responses. This evidence indicates that cardiac conducting tissue pathophysiology is widespread in complete heart bolck. The present work suggests that consideration of the ventricular pacemaker function is important in assessing liability to syncope in complete heart block. While patients with Adams-Stokes attacks require pacing it is suggested that all asymptomatic patients with complete heart block and those with minor symptoms are assessed using studies of both ventricular pacemaker function and site. A low risk group not requiring a pacemaker may emerge after sufficient follow-up assessment.  (+info)

Complete heart block and systemic lupus erythematosus. (5/27)

An 18-year-old girl with systemic lupus erythematosus developed progressive electrocardiographic abnormalities over a period of 16 years, culminating in complete heart block with Adams-Stokes attacks. A permanent ventricular pacing system was implanted successfully.  (+info)

Delay and block of cardiac impulse caused by enhanced phase-4 depolarization in the His-Purkinje system. (6/27)

The underlying mechanism of bradycardia-dependent bundle-branch and paroxysmal atrioventricular block appears to be enhancement of phase-4 depolarization in a branch or in a natural or acquired monofascicular pathway. Clinical records of these forms of impaired conduction occurring in the bundle-branches, with either longer or shorter cardiac cycle lengths, are presented and analysed. These also include the combination of Mobitz typw I atrioventricular block with variable degrees of bundle-branch block, as a representative example of narrow ventricular escape beats firing in the zone where prominent diastolic depolarization is present.  (+info)

THE IMPLANTABLE CARDIAC PACEMAKER. (7/27)

The transistorized implanted pacemaker is proving to be an effective and reliable method for long-term pacing of the heart. All patients suffering from Stokes-Adams seizures were first given a trial period of conservative therapy, including isoproterenol (Isuprel), ephedrine, atropine and steroids. Twenty-four pacemaker implants were performed on 23 patients over a 21-month period. The preoperative insertion of a pacemaker cardiac catheter was a very valuable safety precaution. In this way the heart could be safely and reliably paced during the period of preoperative assessment and during the critical periods of anesthetic induction and thoracotomy. Infection did not occur, probably because of careful gas sterilization of the units. Various models of pacemakers are compared, and the reasons for two pacemaker failures are presented. There were two early deaths and one late death in the series. The relationship of progressive coronary disease to recent infarction is stressed. Patients having intermittent heart block frequently showed the picture of "competing pacemakers" postoperatively, but without deleterious effect. Twenty patients, between 54 and 88 years of age, are alive and well at the time of reporting, with excellent pacemaker response and no further Stokes-Adams attacks.  (+info)

INDICATIONS FOR TREATMENT OF COMPLETE ATRIOVENTRICULAR DISSOCIATION. (8/27)

FOR PURPOSES OF CORRECT TREATMENT IT IS IMPORTANT TO RECOGNIZE THAT PATIENTS WITH COMPLETE ATRIOVENTRICULAR DISSOCIATION FALL INTO THREE GROUPS: Group I-established third-degree heart block with and without Stokes-Adams attacks; Group II-periodic third-degree heart block with and without Stokes-Adams attacks; Group III-established third-degree heart block with cardiac failure. Most patients in Group I present no technical problems when a pacemaker is implanted. In Group II it is advisable to insert a temporary intracardiac catheter electrode and maintain a rate of 60 to 64 during the periods of third-degree heart block. Sudden reversion, in this group, from sinus rhythm can be fatal. Group III patients will often require a pacemaker set in excess of 74 beats until they are free of cardiac failure. Fifteen of 20 patients with complete atrioventricular dissociation showed marked functional improvement after insertion of a pacemaker. The development, in our laboratory, of a 4'' portable pacemaker impulse detector has been invaluable in locating the cause of failure in an implanted pacemaker.  (+info)

Stokes-Adams syndrome (alternative eponyms include Adams-Stokes syndrome, Gerbezius-Morgagni-Adams-Stokes syndrome and Gerbec-Morgagni-Adams-Stokes syndrome) is a periodic fainting spell in which there is a periodic onset and offset of blockage of heart due to disorder of heart rhythm that may last for seconds, hours, days, or even weeks before the conduction returns. Named after two Irish physicians, Robert Adams (1791-1875) and William Stokes (1804-1877), the first description of the syndrome was published in 1717 by the Carniolan physician of Slovene descent Marko Gerbec, which was 44 years after its publication quoted by Giovanni Battista Morgagni. It is characterised by decrease in cardiac output and loss of consciousness due to a transient arrhythmia. For example, bradycardia due to complete heart block. Typically an attack occurs without warning, leading to sudden loss of consciousness. Prior to an attack, a patient may be pale with hypoperfusion. Normal periods of unconsciousness last ...
Adams-Stokes Syndrome: A condition of fainting spells caused by heart block, often an atrioventricular block, that leads to BRADYCARDIA and drop in CARDIAC OUTPUT. When the cardiac output becomes too low, the patient faints (SYNCOPE). In some cases, the syncope attacks are transient and in others cases repetitive and persistent.

Levs disease (or Lenegre-Lev syndrome) is an acquired complete heart block due to idiopathic fibrosis and calcification of the electrical conduction system of the heart. Levs disease is most commonly seen in the elderly, and is often described as senile degeneration of the conduction system. One form has been associated with SCN5A. It was described independently by Maurice Lev and Jean Lenègre in 1964, but the condition is generally called after Lev. Stokes-Adams attacks can be precipitated by this condition. These involve a temporary loss of consciousness resulting from marked slowing of the heart when the atrial impulse is no longer conducted to the ventricles. This should not be confused with the catastrophic loss of heartbeat seen with ventricular fibrillation or asystole. Schott JJ, Alshinawi C, Kyndt F, et al. (1999). "Cardiac conduction defects associate with mutations in SCN5A". Nat. Genet. 23 (1): 20-1. doi:10.1038/12618. PMID 10471492. Lev M. Anatomic basis for atrioventricular ...
As the conduction delay time can be adjusted by the heart rate in DDD-type cardiac pacing, due to the recent technological development of the pacemaker system, the co-relationship between cardiac output and AV conduction delay time is being actively studied. Up to now, in order to determine the most proper AV conduction delay time, according to heart rate in the application of the artificial cardiac pacemaker, studies have been conducted using such means as systolic time interval4,5), echocardiogram6), Doppler echocardiogram7,8), radionuclide ventriculogram9) and hemodynamic study10,11).. The programmable dual chamber cardiac pacemaker can sense and pace both the atrium and ventricle by controlling the AV conduction delay time in many ways. The artioventricular synchrony aims that the atrium can play an assistant role for the cardiac output by contracting atrium and ventricle at proper intervals and therefore, the cardiac output can be improved if the synchrony has been adequately adjusted in ...
A watch battery or button cell is a small single cell battery shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high - resembling a button. A metal can forms the bottom body and positive terminal of the cell. An insulated top cap is the negative terminal. Button cells are used to power small portable electronics devices such as wrist watches, pocket calculators, artificial cardiac pacemakers, implantable cardiac defibrillators, automobile keyless entry transmitters, and hearing aids. Wider variants are usually called coin cells. Devices using button cells are usually designed around a cell giving a long service life, typically well over a year in continuous use in a wristwatch. Most button cells have low self-discharge and hold their charge for a long time if not used. Relatively high-power devices such as hearing aids may use a zinc-air battery which have much higher capacity for a given size, but dry out after a few weeks even if ...

Epinephrine is indicated for intravenous injection in treatment of acute hypersensitivity, treatment of acute asthmatic attacks to relieve bronchospasm, and treatment and prophylaxis of cardiac arrest and attacks of transitory atrioventricular heart block with syncopal seizures (Stokes-Adams Syndrome). The actions of epinephrine resemble the effects of stimulation of adrenergic nerves. To a variable degree it acts on both alpha and beta receptor sites of sympathetic effector cells. Its most prominent actions are on the beta receptors of the heart, vascular and other smooth muscle. When given by rapid intravenous injection, it produces a rapid rise in blood pressure, mainly systolic, by (1) direct stimulation of cardiac muscle which increases the strength of ventricular contraction, (2) increasing the heart rate and (3) constriction of the arterioles in the skin, mucosa and splanchnic areas of the circulation. When given by slow intravenous injection, epinephrine usually produces only a moderate ...

Permanent artificial pacemaking has been undertaken in 13 patients with complete heart block for repeated Stokes-Adams attacks or intractable cardiac failure.
Artificial cardiac pacemakers are most commonly used in the management of symptomatic bradycardias. These pacemakers provide electrical stimuli to the atria or ventricles or both at a desired rate to cause them to contract regularly at that rate. On the electrocardiogram, these electrical impulses are seen as pacemaker spikes identified by their abrupt vertical spike (arrows below), preceding the atrial or ventricular complex, depending on which chambers the pacemaker is responsible for. In this example, a pacemaker has been inserted which is responsible for providing a regular ventricular rhythm (wide, bizarre QRS complex - circled below). No atrial contractions are present. ...

Recognition of normal waves and a "quick and dirty" way to determine axis is presented. Bundle branch block patterns and hemiblocks are reviewed using 12-lead tracings. Recognition of ischemia, injury and infarction is accomplished using a pathophysiologic approach to enhance understanding of the mechanism of the condition and then correlate it to the changes seen on the 12-lead. Chamber hypertrophy, electrolyte imbalances, and drug effects are also reviewed using patient assessment parameters and changes seen in the electrical system of the heart. We award 6.75 CE credits for this online course.. ...
Downloadable (with restrictions)! Can the presence of nontraded consumption goods explain the high degree of home bias displayed by investor portfolios? We find that the answer is no, so long as individuals have access to free international trade in financial assets. In particular, it is never optimal to exhibit home bias with respect to domestic traded-good equities. By contrast, an optimal portfolio may exhibit substantial home bias with respect to nontraded-good equities, although this result requires a very low degree of substitution between traded and nontraded goods in the utility function. Further, our analysis uncovers a second puzzle: the composition of investors portfolios appears to be strongly at variance with the predictions of the model that incorporates nontraded goods.

Transient complete heart block - What is complete heart block? Heart block. Third-degree atrioventricular block or complete heart block, is a disorder of the cardiac conduction system where there is no conduction through the atrioventricular node. Therefore, complete dissociation of the atrial and ventricular activity exists. It results from various pathologic states causing infiltration, fibrosis, or loss of connection in portions of the healthy conduction system.
A family is reported in which two siblings had congenital complete heart block with resultant congestive heart failure, the father and paternal grandfather show adult-onset conduction defects, and the mother has systemic lupus erythematosis. The interaction of heredity and environment is discussed in this context. A review of the literature on familial complete heart block suggests that so-called pure congenital-onset familial heart block, originally felt to be genetic, may in fact have an important enivronmental component, specifically related to ongoing maternal factors such as systemic lupus erythematosis. ...

An artificial cardiac pacer which in the absence of natural cardiac electrical activity provides stimulating electrical pulses to the heart at a fixed rate. The stimulating pulses preferably are obtained from a digital clock integrated circuit including a stable frequency source such as a quartz crystal and a binary frequency divider to yield the desired pulse rate. In response to a natural heart signal, a circuit in the pacer inhibits any stimulating pulse that occurs at that instant of time, and for a predetermined interval of time thereafter to provide an adequate safety margin.

Electrical-mechanical relationships of the canine heart were studied using simultaneous right and left intraveutricular pressures. In the control tracings, there was usually some asynchrony in the onset of ventricular isometric contraction with the right ventricle following the left ventricle. Right bundle-branch block and left bundle-branch block produced a delay in the onset of isometric contraction of the homolateral ventricle. A change in contour of the right intraventricular curve was frequently seen with right, bundle-branch block.. ...

The spread of Dengue virus infection is reaching pandemic proportions. Dengue is usually dreaded for causing shock due to capillary leakage. However the clinical spectrum of dengue is vast and the newly incorporated expanded dengue syndrome introduces a wide range of presentations that are rarely observed and appreciated but nevertheless have the potential to cause significant morbidity and even mortality. Cardiac involvement in dengue is one such example. A 26 year old South-Asian female presented in a state of haemodynamic shock with a history of fever and use of non-steroidal anti inflammatory drugs. Dengue was suspected clinically and later confirmed. Following stabilization and while still in the febrile phase the patient developed bradycardia with dynamic electrocardiogram changes which evolved into complete heart block. However there was no circulatory compromise. Clinical picture was further complicated by the development of dengue haemorhaghic fever and cautious fluid resuscitation was carried

Start in alphabetical order, sewing section B to section A. Iron flat, trim edges where necessary, and then sew section C to the whole group. This is the only time you will need to really worry about lining up any seams perfectly. Where piece 2A and 1C come together in the lower right hand corner must be just right, or the heart shape will be off when you are done. However, as I discovered, just lining up the seams exactly doesnt do the job. I ended up folding back the material to approximate a 1/4 edge seam, and then laid it over the fabric to line up the edges, and then pinned it there. Sewing it wrong first actually helped with this as I could then follow the little holes left in the fabric for my 1/4 inch line ...

A rate responsive cardiac pacemaker for providing an optimized pacing rate of stimulation pulses as a function of at least one selected rate control parameter. Each rate control parameter has a value which varies as a function of changes in a patients physiologic demand and includes a sensor system for sensing the rate control parameter value and for providing a sensor output representative thereof. The cardiac pacemaker also includes control circuitry which includes a rate response defining means for deriving desired pacing rates as a function of the sensor output and an achievement monitoring means that has a predetermined achievement criterion, for monitoring the relationship between the derived pacing rates and the achievement criterion over an optimization period. An output circuitry provides optimized pacing rates as a function of the desired pacing rates, such optimization being accomplished by adjusting the rate response function for each sensor as a function of of the monitored achievement

In this study we have demonstrated the feasibility of SRS for AV node ablation in an intact porcine model, and, to our knowledge, we are the third group to use radiation therapy for AV node ablation.4 Sharma et al attempted AV node ablation in 2 pigs: 1 procedure was successful with 70‐Gy ablation, whereas the other failed due to pacemaker infection.4 In our study we used doses of 35 to 40 Gy to successfully achieve complete heart blocks in 5 pigs. The pig in the Sharma et al study had AV node conduction changes earlier than 35 days after the procedure, which is likely related to the higher dose of radiation used. Our study is significant in that we demonstrated complete heart block in 5 pigs with a lower dose of radiation. Another group from the Mayo Clinic published their data recently in April 2017 on the external arrhythmia ablation using photon beams and achieved 86% success in achieving complete heart block in an intact animal model with a dose deescalation from 55 to 25 Gy.5 Our study ...

Syncope affects about 50% of Canadians, is the cause of 1 - 2% of all emergency room visits, and probably is responsible for CDN $250 million in health care spending each year. It is associated with decreased quality of life, trauma, loss of employment, and limitations in daily activities. It is a particular problem for older people, partly because of increased frailty, and partly because of a difficult differential diagnosis. One of the causes in older adults is intermittent complete heart block in the setting of bifascicular heart block, but they may also faint due to a variety of tachyarrhythmias, sick sinus syndrome, and several neurally mediated syncopes.

Performing the high rate test Masini and Dianda (1977) found normal values in most oftheir patients who were classified as "functional sinus bradycardia . " There was no correlation between the SACT and the symptoms of the patients. The same was true for the SNRT (Figure 7). The problem is that in most of the patients we do not know the mechanisms of syncope. During our long-term tape recordings we found that in some patients the symptoms are not related to rhythm disturbances. The ...

After a few weeks, palpitations disappeared completely, but rapid heartbeat only partially mitigated. I dont think there is anything wrong with having a moderately elevated heart rate, though. Ive been on TCAs for over 30 years. Ill let you know after my first stress-test. My EKGs are normal. All I can say is that combining Parnate + desipramine sure packed a wallop the first time they were used together in me. My autonomic nervous system felt like it was being fried. Good stuff. I reached remission within a few months (1987). To keep a long story from becoming longer, I never responded to that treatment again.. It is a matter of risk/cost/benefit.. I hope you are doing reasonably well. It is relative, I guess. When someone asks me how I am doing, I usually answer that I could be doing worse - knowing that I could be ...
