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.

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)

Typically an attack occurs without warning, leading to sudden loss of consciousness.[4] Prior to an attack, a patient may be pale with hypoperfusion. Abnormal movements may be present, typically consisting of twitching after 15-20 seconds of unconsciousness. (These movements, which are not seizures, occur because of brainstem hypoxia and not due to cortical discharge as is the case for epileptiform seizures). Breathing typically continues normally throughout the attack, and, upon recovery, the patient becomes flushed as the heart rapidly pumps the oxygenated blood from the pulmonary beds into the systemic circulation, which has become dilated due to hypoxia.[5] As with any syncopal episode that results from a cardiac dysrhythmia, the fainting does not depend on the patients position. If it occurs during sleep, the presenting symptom may simply be feeling hot and flushed on waking.[5][6] ...
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 ...
Lithium cells, if ingested, are highly dangerous. In the pediatric population, of particular concern is the potential for one of these batteries to get stuck in the oesophagus.[11][12] Such impactions can rapidly devolve and cause severe tissue injury in as little as two hours.[12][17][18] The damage is not caused by the contents of the battery, but by the electric current that is created when the anode (negative) face of the battery comes in contact with the electrolyte-rich esophageal tissue. The surrounding water undergoes a hydrolysis reaction that produces a sodium hydroxide (caustic soda) build-up near the batterys anode face (cathodic reaction in the electrolyte). This results in the liquefactive necrosis of the tissue, a process whereby the tissue effectively is melted away by the alkaline solution.[17] Severe complications can occur, such as erosion into nearby structures like the trachea or major blood vessels, the latter of which can cause fatal bleeds. While the only cure for an ...

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.

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.

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. ...

Progressive familial heart block type II (PFHB2) is an autosomal dominant disorder, similar to type I progressive familial heart block (PFHB1; see 113900). The pattern of PFHB2, however, tends to develop along the lines of a sinus bradycardia with a left posterior hemiblock, presenting clinically as syncopal episodes, Stokes-Adams seizures, or sudden death when complete heart block supervenes (Brink and Torrington, 1977).

This online course enables the bedside professional to perform an interpretation of a 12-lead ECG and apply it to the clinical setting. 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.(This abstract was borrowed from another version of this item.)
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.
At a quick glance, you will immediately notice that there seemed to be no association between the P and QRS. So, you will jump into the conclusion that this is complete heart block (CHB) or third degree AV block. However, for CHB the RR interval MUST BE REGULAR. It is because supraventricular impulses are blocked and the ventricles are depolarized by either a junctional or ventricular pacemaker and they generate a regular RR to interval. In the case presented, the RR interval is irregular. Thus, we can conclude that SOME OF THE IMPULSES were able to conduct to ventricles. R3 and R6 are captured beats or sinus beats that were conducted to the ventricles (PRI of about 0.40 sec). Hence, this is not complete heart block. This is called HIGH-GRADE or ADVANCED SECOND-DEGREE AV BLOCK. ...
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.

Heart block occurs when the electrical signals that tell the heart to contract are delayed or blocked between the upper chambers (atria) and lower chambers (ventricles). This results in a slow or irregular heartbeat and depending on the degree of heart block you may require treatment or a pacemaker.. The condition can be present from birth, known as congenital heart block, or it can develop later in life.. Heart block is commonly seen in patients as they get older but can be caused by infection (Lyme disease), high blood pressure, exposure to toxic substances or powerful drugs such as those used to treat cancer or coronary heart disease. There are a large number of cause of heart block and occasionally it is not possible to delineate the cause. However, even when the clear cause is not known, given the consequences, this doesnt alter the treatment which in cases of advanced heart block is a pacemaker. ...

A case for an implantation in a human or animal body. The case comprises a rigid plastics substrate which defines a chamber and a platinum skin arranged to overlie the substrate, the skin being formed in two or more pieces welded together--for instance by electron beam welding--to form a hermetically sealed case. The platinum skin should be from 0.1875 mm to 0.5 mm thick and is biocompatible, rendering the case suitable for implanting and containing a power pack and electronic package for a cardiac pacemaker.
It is disease of electrical conducting system of heart, in which impulse from atria to ventricle through AV node travels slowly, taking more than the normal time of 20 milliseconds.
When you have heart block, there is interference with the electrical signals that usually move from the top chambers of your heart to the bottom chambers, telling your heart when to beat.
Heart block is a problem that occurs with the hearts electrical system. It occurs when the electrical signal is slowed or disrupted as it moves through the heart.
When you have heart block, there is interference with the electrical signals that usually move from the top chambers of your heart to the bottom chambers, telling your heart when to beat.
