Sick Sinus Syndrome
A condition caused by dysfunctions related to the SINOATRIAL NODE including impulse generation (CARDIAC SINUS ARREST) and impulse conduction (SINOATRIAL EXIT BLOCK). It is characterized by persistent BRADYCARDIA, chronic ATRIAL FIBRILLATION, and failure to resume sinus rhythm following CARDIOVERSION. This syndrome can be congenital or acquired, particularly after surgical correction for heart defects.
Cardiac Pacing, Artificial
Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.
Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.
A transient loss of consciousness and postural tone caused by diminished blood flow to the brain (i.e., BRAIN ISCHEMIA). Presyncope refers to the sensation of lightheadedness and loss of strength that precedes a syncopal event or accompanies an incomplete syncope. (From Adams et al., Principles of Neurology, 6th ed, pp367-9)
The small mass of modified cardiac muscle fibers located at the junction of the superior vena cava (VENA CAVA, SUPERIOR) and right atrium. Contraction impulses probably start in this node, spread over the atrium (HEART ATRIUM) and are then transmitted by the atrioventricular bundle (BUNDLE OF HIS) to the ventricle (HEART VENTRICLE).
Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.

Arterial thromboembolism in patients with sick sinus syndrome: prediction from pacing mode, atrial fibrillation, and echocardiographic findings. (1/234)OBJECTIVE: To evaluate whether thromboembolism in sick sinus syndrome can be predicted by pacing mode, atrial fibrillation, or echocardiographic findings. METHODS: Patients were randomised to single chamber atrial (n = 110) or ventricular (n = 115) pacing. They were divided into subgroups with and without brady-tachy syndrome at time of randomisation. The occurrence of atrial fibrillation and thromboembolism during follow up were investigated and compared with echocardiographic findings. RESULTS: The annual risk of thromboembolism was 5.8% in patients with brady-tachy syndrome randomised to ventricular pacing, 3.2% in patients without brady-tachy syndrome randomised to ventricular pacing, 3% in patients with brady-tachy syndrome randomised to atrial pacing, and 1.5% in patients without brady-tachy syndrome randomised to atrial pacing. In atrial paced patients without brady-tachy syndrome at randomisation and without atrial fibrillation during follow up, the annual risk of thromboembolism was 1.4%. Left atrial size measured by M mode echocardiography was of no value in predicting thromboembolism. CONCLUSIONS: Arterial thromboembolism in patients with sick sinus syndrome is very common and is associated primarily with brady-tachy syndrome at randomisation and with ventricular pacing. The risk of thromboembolism is small in atrial paced patients in whom atrial fibrillation has never been documented. (+info)
Acute performance of steroid-eluting screw-in leads for atrial free wall pacing. (2/234)The aim of this study was to clarify the acute performance of steroid-eluting screw-in leads in comparison with that of nonsteroid screw-in leads for atrial free wall pacing. In 114 cases (68 males, 46 females, average age 70 years) with atrial free wall pacing by screw-in leads, pacing thresholds and P-wave amplitudes were compared at the time of implantation and 1 week later between 68 cases of nonsteroid and 46 cases of steroid-eluting screw-in leads. No significant differences were seen between the 2 groups at implantation in either voltage or current thresholds measured at pulse widths of 0.1, 0.3, 0.6, 1.0, 2.0 ms, or P-wave amplitudes. Pulse width thresholds at outputs of 2.5 V and 5.0 V were significantly lower for steroid leads 1 week after implantation (2.5 V: 0.34+/-0.27 ms nonsteroid vs. 0.12+/-0.08 ms steroid, p<0.001; 5.0 V: 0.12+/-0.08 ms nonsteroid vs. 0.06+/-0.02 ms steroid, p<0.01). P-wave amplitudes after 1 week were significantly higher for steroid leads (2.6+/-0.7 mV nonsteroid vs 3.0+/-1.2 mV steroid, p<0.001). Threshold rise, including pacing failure, was observed in 15 (22%) of the non-steroid leads, but in only 1 (2%) of the steroid leads. In conclusion, steroid-eluting screw-in leads suppress the acute rise of pacing thresholds in the right atrial free wall and their acute performance is better than that of non-steroid leads. These results suggest that appropriate low-output atrial pacing is feasible immediately after implantation. (+info)
Exercise-induced uncommon atrioventricular nodal reentrant tachycardia with sick sinus syndrome: a case report. (3/234)Exercise seldom provokes tachycardia in patients with paroxysmal supraventricular tachycardia (PSVT). This report presents a case of exercise-induced uncommon atrioventricular nodal reentrant tachycardia (AVNRT) with sick sinus syndrome. Treadmill exercise testing provoked AVNRT of long RP' with good reproducibility. Uncommon AVNRT was confirmed by the lack of atrial pre-excitation during PSVT and para-Hisian pacing. The patient has been successfully treated with verapamil and DDD pacing for 5 years. (+info)
Effect of physiological mechanical perturbations on intact human myocardial repolarization. (4/234)OBJECTIVE: The objective of this study was to investigate the relationship between acute decreases in right ventricular volume during Valsalva strain (with resultant changes in autonomic neural tone) and measures of local endocardial repolarization time independent of heart rate and autonomic neural tone. METHODS: Patients implanted with a stimulus to T wave (Stim-T) sensing pacemaker specially adapted to output a validate measure of beat to beat local repolarization (n = 9) performed Valsalva manoeuvers (40 mmHg for 15 s) while paced at a cycle length of 500 ms. Stim-T intervals were measured before and after autonomic blockade (Block: 0.03 mg/kg i.v. atropine +/- 0.15 mg/kg propranolol). Right ventricular end diastolic volume was estimated by simultaneous 2D-echocardiography. RESULTS: Without autonomic blockade, compared to baseline, repolarization significantly prolonged during Valsalva strain (1.1 +/- 0.7%) and shortened during release (-1.4 +/- 1.0%). After block, strain related repolarization prolongation was also observed (1.0 +/- 0.6%), with significantly less release related repolarization shortening (-0.8 +/- 0.8%) compared to pre-block (P < 0.05). Right ventricular end diastolic volume decreased during strain by 11 +/- 10 and 9 +/- 16% from baseline, pre- and post-block respectively (P < 0.05). CONCLUSION: In a chronically instrumented human model, an acute physiologic volume reduction modestly prolongs right ventricular repolarization independent of changes in rate or autonomic tone.

Concerns about sources of electromagnetic interference in patients with pacemakers. (5/234)Electromagnetic noise is rapidly increasing in our environment so electromagnetic interference (EMI) with pacemakers (PM) may become a more important problem despite technological improvements in PM. The aim of this study was to evaluate the kinds of EMI which affect the quality of life of PM patients. The participants (1,942 Japanese Association for Pacemaker Patients: Pacemaker-Tomonokai) were asked to respond to a questionnaire about their major EMI troubles, and 1,567 patients (80.7%) responded by mail. The main concerns were from mobile telephones (MT) (39%), magnetic resonance imaging (MRI) (17%), electronic kitchen appliances, automobile engines and high voltage power lines. If possible, PM implantation sites should be carefully selected not only according to the physician's convenience but also considering information on each patient's habits and physical limitations.

Regional myocardial blood flow in patients with sick sinus syndrome randomized to long-term single chamber atrial or dual chamber pacing--effect of pacing mode and rate. (6/234)OBJECTIVES: This study aimed to evaluate regional myocardial blood flow (MBF) and global left ventricular ejection fraction (LVEF) during chronic pacing in patients with sick sinus syndrome (SSS) randomized to either single chamber atrial (AAI) or dual chamber (DDD) pacing. BACKGROUND: Experimental studies indicate that chronic pacing in the right ventricular apex changes regional MBF, thereby compromising left ventricular function. METHODS: Thirty patients (age 74 +/- 10 years) were randomized to AAI (n = 15) or DDD (n = 15) pacemakers. After 22 +/- 7 months of pacing, MBF was quantified with 13N-labeled ammonia positron emission tomography scanning at 60 beats per min and 90 beats per min. Patients in the DDD group furthermore underwent MBF measurement at temporary AAI pacing, 60 beats per min. Myocardial blood flow was assessed in the anterior, lateral, inferior and septal regions, and the global mean MBF was calculated. Left ventricular ejection fraction was determined by echocardiography at pacemaker implantation and at the time of MBF measurements. RESULTS: Myocardial blood flow at rates 60 and 90 beats per min did not differ between the AAI and DDD groups. During temporary AAI pacing in the DDD group, MBF was significantly higher than during DDD pacing in both the inferior (p = 0.001) and septal (p = 0.004) regions and also globally (0.61 +/- 0.15 vs. 0.53 +/- 0.13 mL x g(-1) x min(-1), p = 0.005). In the DDD group, LVEF decreased from pacemaker implantation to time of MBF measurements (0.61 +/- 0.09 vs. 0.56 +/- 0.07, p = 0.013). Left ventricular ejection fraction during temporary AAI pacing at time of MBF measurements was not different from LVEF at pacemaker implantation. CONCLUSIONS: In patients with SSS, chronic DDD pacing reduced inferior, septal and global mean MBF as well as LVEF, as compared with temporary AAI pacing. The LVEF reversed to baseline level during temporary AAI pacing despite 22 months of permanent ventricular pacing preceding it. Augmenting pace rate to 90 beats per min increased MBF equally in the two treatment groups. (+info)
Exchange of pacing or defibrillator leads following laser sheath extraction of non-functional leads in patients with ipsilateral obstructed venous access. (7/234)Occlusion of the subclavian or brachiocephalic vein in pacemaker or defibrillator patients prohibits ipsilateral implantation of new leads with standard techniques in the event of lead malfunction. Three patients are presented in whom laser sheath extraction of a non-functional lead was performed in order to recanalise the occluded vein and to secure a route for implantation of new leads. This technique avoids abandoning a useful subpectoral site for pacing or defibrillator therapy. The laser sheath does not affect normally functioning leads at the same site. (+info)
Permanent pacemaker insertion in a district general hospital: indications, patient characteristics, and complications. (8/234)This report reviews the experience of permanent pacemaker insertion in a district general hospital (catchment population of 350 000) and makes a comparison with the national database and other hospitals in the UK. METHODS: The records of all patients receiving a permanent pacemaker in the inclusive period January 1996 to December 1998 were reviewed. Data collected included number of patients paced each year, age, sex, indications, and complications. RESULTS: In the three years reviewed 200 patients received new permanent pacemakers, a rate of 190 per million population per year, which is similar to the national implantation rate of permanent pacemakers but lower than that of most European countries (see discussion). The majority of patients paced were elderly (75% were above the age of 70 years). Atrioventricular block (including complete heart block, 45%, and Mobitz type 2 block, 12.5%) was the commonest indication for permanent pacemaker insertion, followed by sick sinus syndrome (25%) and these findings are comparable to those reported previously. However, carotid sinus syndrome was responsible for 16% of the patients paced and this was higher than that reported in the national database (6.5%). Only 1% of the pacemaker modes used was inappropriate and the complication rate was low at 3%. CONCLUSIONS: This report confirms that permanent pacemaker insertion can be effectively and safely provided locally for the increasingly ageing population. The implantation rate both locally and nationally is still much lower than that of some countries in Europe. (+info)

Diagnosis and Treatment of Sick Sinus Syndrome - American Family Physician
Sick sinus syndrome comprises a variety of conditions involving sinus node dysfunction and commonly affects elderly persons. While the syndrome can have many causes, it usually is idiopathic. Patients may experience syncope, pre-syncope, palpitations, or dizziness; however, they often are asymptomatic or have subtle or nonspecific symptoms. Sick sinus syndrome has multiple manifestations on electrocardiogram, including sinus bradycardia, sinus arrest, sinoatrial block, and alternating patterns of bradycardia and tachycardia (bradycardia-tachycardia syndrome). Diagnosis of sick sinus syndrome can be difficult because of its nonspecific symptoms and elusive findings on electrocardiogram or Holter monitor. The mainstay of treatment is atrial or dual-chamber pacemaker placement, which generally provides effective relief of symptoms and lowers the incidence of atrial fibrillation, thromboembolic events, heart failure, and mortality, compared with ventricular pacemakers.
Sick sinus syndrome associated with anti-programmed cell death-1 | Journal for ImmunoTherapy of Cancer | Full Text
Use of anti-programmed cell death-1 (anti-PD-1) has been successful in treating many types of cancers. Despite its promising efficacy, immune-related adverse events are still a major concern. Immune-related cardiotoxicity, which is rare but fatal, has recently become a focus of attention. Cardiotoxicities including myocarditis, cardiomyopathy, cardiac fibrosis, heart block and cardiac arrest have been reported. Of these toxicities, myocarditis is often accompanied by dysrhythmia. The presentation of sick sinus syndrome as an immune-related adverse event has not yet been reported. Here, we reported the first case of sick sinus syndrome, a rare toxicity induced by anti-PD-1. A 42-year-old male patient who had metastatic hepatocellular carcinoma failed treatment with sorafenib. Pembrolizumab at a fixed dose of 100 mg every three weeks was given. His heart rate gradually slowed down and he presented sick sinus syndrome with a lowest heart rate of 38 bpm after six cycles of pembrolizumab. He denied chest

Introduction -. Abnormalities of desmosomes, more specifically mutations in the desmoplakin (DSP) gene, have been shown to cause not only arrhythmogenic right ventricular cardiomyopathy (ARVC) but also sick sinus syndrome (SSS) as well. Although various ARVC overlap syndromes have been described, its association with sinus node dysfunction is not documented. In this report, we describe an autosomal dominant missense mutation in the DSP gene in a proband with sick sinus syndrome and features of ARVC on cardiac MRI.. Clinical case -. A 70 year old man presented with a recurrent episodes of syncope, that were historically suggestive of an arrhythmic etiology. He had a history of systemic hypertension which was under adequate control with ACE inhibitors. His 2D Echocardiogram (ECHO) revealed a structurally normal heart. During his evaluation of syncope, his baseline electrocardiogram (ECG), head up tilt test, brain imaging, and electroencephalography were non-contributory. Cardiac MRI(CMR) ...

The Danish Multicenter Randomised Study on AAI Versus DDD Pacing in Sick Sinus Syndrome - Full Text View - ClinicalTrials.gov
Background In patients with isolated SSS, who need pacemaker treatment, any pacemaker can be used to treat the symptomatic bradycardia: a single chamber atrial (AAI) pacemaker, a single chamber ventricular (VVI) pacemaker, or a dual chamber (DDD) pacemaker. In the USA and in most European countries, DDD pacing is used in most cases. It is now known from the Danish AAI/VVI trial, that AAI pacing is superior to VVI pacing, since VVI pacing is associated with a higher mortality and a higher incidence of atrial fibrillation, thromboembolic complications and heart failure. This confirms previous findings in observational studies. Therefore, VVI pacing should no longer be used in patients with SSS.. The main argument for using DDD pacing is the concern, that the patients will develop symptomatic atrioventricular (AV) block. In the Danish AAI/VVI trial, the risk of AV block was approximately 0.6% per year, which is equivalent to the risk found in a larger meta analysis. This is only a little higher ...
Sick Sinus Syndrome in HCN1-Deficient MiceClinical Perspective | Circulation
Here, we show that HCN1 channels make up a physiologically relevant component of If in the SAN. If was reduced by ≈30% in HCN1−/− SAN cells, and the activation kinetics of the remaining If was significantly slowed down. Our results also suggest that HCN1 is functionally important in spindle and elongated primary pacemaker cells of the central SAN. The main cardiac phenotype of the HCN1−/− mouse is a pronounced sinus node dysfunction characterized by impaired impulse formation and sinoatrial conduction, resulting in bradycardia, sinus arrhythmia, and recurrent sinus pauses. Hemodynamically, these changes lead to a relevant reduction in cardiac output.. Several mechanisms may contribute to this complex phenotype. First, a reduction in If density is an important factor that could contribute to or explain the bradycardia observed in HCN1−/− mice. Heterologous expression studies and analysis of neuronal hyperpolarization-activated currents predominantly carried by HCN1 revealed that the ...

Sick Sinus Syndrome in HCN1-Deficient Mice | Circulation
Background-Sinus node dysfunction (SND) is a major clinically relevant disease which is associated with sudden cardiac death and requires surgical implantation of electrical pacemaker devices. Frequently, SND occurs in heart failure and hypertension, conditions that lead to electrical instability of the heart. While the pathologies of acquired SND have been extensively studied, little is known about the molecular and cellular mechanisms that cause congenital SND. Methods and Results-Here, we show that the HCN1 protein is highly expressed in the sinoatrial node and is colocalized with HCN4, the main sinoatrial pacemaker channel isoform. To characterize the cardiac phenotype of HCN1-deficient mice a detailed functional characterization of pacemaker mechanisms in single isolated sinoatrial node cells, explanted beating sinoatrial node preparation, telemetric in vivo electrocardiography, echocardiography and in vivo electrophysiology was performed. Based on these experiments we demonstrate that mice ...
Sick Sinus Syndrome (SSS) | UpBeat
The sinus node is a specialized group of cells in the upper chamber of the heart, the right atrium, that creates electrical signals that regulate the pace and rhythm of the heartbeat. Normally, the sinus node produces a regular, steady pattern of signals. With SSS, the pattern is irregular. The normal heart beat should increase with activity and decrease with rest and sleep. With SSS, this function is disrupted, with a heart beat that is too slow for the patients level of activity. ...
Assessment of myocardial adrenergic innervation in patients with sick sinus syndrome: effect of asynchronous ventricular...
As far as we know, this study is the first to examine the effect of permanent dual chamber pacing on myocardial perfusion and adrenergic innervation before and after pacemaker implantation in humans.. Ventricular pacing through the right ventricular apex-although the site is easily accessible and traditionally used for electrode implantation-results in asynchronous ventricular activation.13 During the last few years, normalisation of ventricular electrical stimulation in paced patients has acquired considerable importance. Other researchers have suggested that ventricular pacing decreases fibre shortening, contractile work, and myocardial blood flow in early activated regions and increases these indices in late activated regions.14 It is also known that long term asynchronous electrical activation leads to asymmetrical changes of left ventricular wall mass induced by regional changes of mechanical load, with the early activated regions having a lower preload than the late activated regions. ...

Sinus node dysfunction - WikiProjectMed
Sinus node dysfunction (SND), also known as sick sinus syndrome (SSS), is a group of abnormal heart rhythms caused by malfunction of the sinoatrial node, the hearts primary pacemaker. Early on symptoms may be few. As the disease progresses syncope may occur. Other symptoms may include lightheadedness, palpitations, or chest pain. The heart may beat insufficiently fast during exercise. Complications may include atrial fibrillation. It involves a slow heart rate with or without periods of a faster heart rate. The slow heart rate may be a sinus bradycardia, sinus pause, or sinoatrial exit block. When periods of a fast heart rate is present it is known as tachy-brady syndrome. The underlying mechanism may include fibrosis, ion channel dysfunction, or remodeling of the sinoatrial node. Other factors that can worsen the condition include medications such as beta blockers or calcium channel blockers, electrolyte abnormalities, low oxygen, and low thyroid. Diagnosis is ...

She met with Dr. Emmanuel Nsah, a cardiologist, at the Peninsula Regional Medical Center in Salisbury and he diagnosed her with a rare diagnosis of Sick Sinus Syndrome, also known as sinus node dysfunction, a collection of heart rhythm disorders that include sinus bradycardia, which slows the heart rate from the natural pacemaker of the heart, or sinus pauses or arrest, which is when the natural pacemaker of the heart stops working for periods of time.. Over time, she tried different remedies but nothing seemed to be working and her heart rate eventually reached the low 30s.. In May, Ehrhart-Knight had her first heart surgery to implant an internal heart monitor. The heart monitor showed that in the course of the day she would have over 150 bradycardic episodes, which means her heart rate would drop under 40 beats per minute..

Sinus node dysfunction in acute myocardial infarction. | Heart
The frequency, clinical course, and prognosis of sinus node dysfunction in 431 patients with acute myocardial infarction admitted to the coronary care unit were studied. Sinus node dysfunction occurred in 20 patients. In 13, the principal manifestation consisted of severe sinus bradycardia. In the remaining 7, periods of bradycardia alternating with episodes of supraventricular tachycardia were noted. Though several of the patients with sinus bradycardia required intravenous atropine or temporary pacing, normal sinus rhythm returned in virtually all during follow-up. The clinical course of patients with both bradycardia and tachycardia was less benign, during the acute phase and during follow-up; 5 of the 6 survivors required continued antiarrhythmic therapy or permanent pacing. The differences in the clinical course between these two groups of patients may reflect distinct underlying pathological changes. The findings in this study suggest that in contrast to sinus bradycardia, the occurrence ...

Ill spare you the pathophysiology lesson. Suffice it to say Zevs heart rate did not improve with the ART, thus giving us one more piece of the puzzle and a differential diagnosis of idiopathic cardiac fibrosis or sick sinus syndrome, two similar conditions that occur occasionally in cocker spaniels. Neither has any definitive treatment other than pacemaker implantation. No one knows exactly why cockers get these problems, but as breed-specific occurrences, it is suspected they are genetic and inheritable. Rarely, cancer or infection may be implicated, but Zev showed no indications of such underlying illnesses.. His mother agonized over the decision. What will happen without a pacemaker? she asked somberly. After discussing Zevs situation with several cardiologists on-line, I answered her question. Sort of.. One cardiologist says that without a pacemaker Zev has a significant risk of sudden death within the next year or two, I stammered. The other cardiologist thinks the prognosis may not ...
IJMS | Free Full-Text | Heart Failure Differentially Modulates Natural (Sinoatrial Node) and Ectopic (Pulmonary Veins)...
Heart failure (HF) frequently coexists with atrial fibrillation (AF) and dysfunction of the sinoatrial node (SAN), the natural pacemaker. HF is associated with chronic adrenergic stimulation, neurohormonal activation, abnormal intracellular calcium handling, elevated cardiac filling pressure and atrial stretch, and fibrosis. Pulmonary veins (PVs), which are the points of onset of ectopic electrical activity, are the most crucial AF triggers. A crosstalk between the SAN and PVs determines PV arrhythmogenesis. HF has different effects on SAN and PV electrophysiological characteristics, which critically modulate the development of AF and sick sinus syndrome. This review provides updates to improve our current understanding of the effects of HF in the electrical activity of the SAN and PVs as well as therapeutic implications for AF.
Can Bradycardia Go Away On Its Own? - caramenggugurkankandungann.com
There are two basic types of bradycardia:Sick sinus syndrome occurs when the sinus node (the hearts own pacemaker) fails and does not reliably trigger heartbeats. … Heart block is a complete or partial interruption of the electrical impulses on their way to the ventricles and results in a slow, unreliable heartbeat ...
ANK2 - Wikipedia
Ankyrin-B is a member of the ankyrin family of proteins. ankyrin-1 has shown to be essential in normal function of erythrocytes; however, ankyrin-B and ankyrin-3 play essential roles in the localization and membrane stabilization of ion transporters and ion channels in cardiomyocytes. Functional insights into ankyrin-B function have come from studies employing ankyrin-B chimeric proteins. One study showed that the death/C-terminal domain of ankyrin-B determines both the subcellular localization as well as activity in restoring normal inositol trisphosphate receptor and ryanodine receptor localization and cardiomyocyte contractility. Further studies have shown that the beta-hairpin loops within the ankyrin repeat domain of ankyrin-B are required for the interaction with the inositol trisphosphate receptor, and a reduction of ankyrin-B in neonatal cardiomyocytes reduces the half-life of the inositol trisphosphate receptor by 3-fold and destabilizes its proper localization; all of ...
Arrhythmias and Dilated Cardiomyopathy | JACC: Journal of the American College of Cardiology
In this issue of the Journal, McNair et al. (12) report the screening of the cardiac sodium channel gene SCN5A in a cohort of patients and families with DCM. Of the 338 subjects from 289 families studied, 15 mutation carriers were found, including 5 separate mutations (1.7%), 3 being novel (12). In 14 of 15 subjects with mutations (93%), arrhythmias were also notable and included supraventricular arrhythmias (13 of 15), sick sinus syndrome (5 of 15), atrial fibrillation (9 of 15), ventricular tachycardia (5 of 15), and conduction disease (9 of 15). The authors have studied the mechanisms involved in the development of these overlapping phenotypes. In nearly 70% of the SCN5A mutations thus far reported to cause DCM, the mutations localize to the highly conserved homologous S3 and S4 transmembrane segments, suggesting a shared mechanism of disruption of the voltage-sensing mechanism of this channel. Hence, the authors intimate a correlation among DCM, arrhythmias, and sodium channel mutations. ...

Drugs Five Years Later: Disopyramide | Annals of Internal Medicine | American College of Physicians
Since disopyramide was introduced 5 years ago, the therapeutic spectrum of this drug in treating patients with ventricular and atrial arrhythmias has been found to be similar to that of the other type I antiarrhythmic drugs, quinidine and procainamide. Disopyramide has the potential to suppress sinus node function and, therefore, must be used cautiously in patients with the sick sinus syndrome. The available data indicate that it can be used safely in patients with bundle branch block and firstdegree or type I second-degree atrioventricular block. Disopyramide has been found at times to precipitate ventricular tachycardia or ventricular fibrillation. Because this drug often causes decompensation in patients with congestive heart failure, it must be used very cautiously, if at all, in such patients. ...

Phenotypic Spectrum of HCN4 Mutations | Circulation: Genomic and Precision Medicine
The hyperpolarization-activated cyclic nucleotide-gated (HCN) cation (Na+/K+) currents (If/Ih) are generated by 4 members of the channel family (HCN1-4).1 These currents contribute to the pacemaker function2 in heart and brain.3 The HCN4 current is known to play a crucial role in the automaticity of the sinus node through the generation of a slow diastolic depolarization during the phase 4 of the cardiac action potential.4 Thus, it is a crucial channel for appropriate pacemaker activity and conduction system function because it facilitates rapid repolarization. Interestingly, HCN4 has been shown to be expressed in essentially the entire heart tissue.5 Mutations in HCN4 have been associated mainly with sick sinus syndrome phenotype6; however, in recent years, a broad spectrum of phenotypes has been reported, including sinus bradycardia,7 inappropriate sinus tachycardia,8 early-onset atrial fibrillation,9,10 atrio-ventricular block,11,12 idiopathic ventricular tachycardia,13 left ventricular ...

Transient sinus node dysfunction after the Cox-maze III procedure in patients with organic heart disease and chronic fixed...
Treatment strategy of sinus node dysfunction after the maze procedure is largely dictated by patients symptoms and electrocardiographic findings. Continuous monitoring of the rhythm and stand by modus of ventricular pacing on demand are important during the early postoperative course after the maze procedure because some of the patients may be intermittently asystole. Sinus arrhythmia, sinus tachycardia, and nonphysiological sinus tachycardia do not need pacemaker implantation (11). Sinus pause or arrest longer than 3 s is rarely an indication for pacemaker implantation in patients with the maze procedure because they were uncommonly associated with symptoms in our patients. However, in patients other than those with the maze procedure, these electrocardiographic findings may be combined with the symptoms and therefore may require pacemaker implantation (24), although some found symptoms to be uncommon during such pauses, and prognosis was not altered by cardiac pacing (25). Nevertheless, ...

File:E299.jpg - ECGpedia
The ventricular rate of the patient is about 72 beats/minute and it would appear that there is a p wave in front of each QRS complex. The pr interval is a little short at about 120 ms. The pacer should have started to pace he atrium when set at 100/min. The failure to do so suggests that the pacing system is non-functional (depleted pacemaker battery, broken lead etc.) or that the pacer is sensing an atrial rhythm faster than 100/min. In this case the pacer is sensing an SVT with an atrial rate of about 150/min. which explains the lack of pacing when the pacer is set to 100/min. The treating physician decided to leave the patient in this rhythm. It is interesting to note that some SVTs and atrial fibrillation can cure a sick sinus patient of their bradycardia and the need for a pacemaker. In those cases though that convert to atrial fibrillation anticoagulants are usually considered. ...
abnormal EKG - Heart & Cardiovascular Disease - HealingWell.com Forum
Hi jhmom, welcome to the heart forum. I have bradycardia (low heart rate) for this I have a pacemaker, Sick Sinus Syndrom and a septial defect. I also have extremely low blood pressure due to an autonomic disorder that presented in august 05. My blood pressures some days get down to 70s/50s (and even lower) and I do pass out when I stand and even sitting up I have hullicunations and such. My bps have always been on the low side but not ever this low before. I have also had MS for over 5 years. When my heart and bp problems started in 8/05 before my diagnosis of the autonomic disorder my doctors had to take me off of each and every medication that I was on at the time as meds can be a huge factor to these type of problems. Also, to assess if there were any drug interactions going on too as over time these can develop even with medications that a person has taken for a while. I would assume that since you have lupus that you are on some medications? What I would say is if you dont have a family ...

Pacemaker, Information about Pacemaker
The rhythmic, regular beating of the heart is controlled by a natural pacemaker--a small patch of cells at the top of the right atrium called the sinus node which sends rhythmic electric impulses along specific conducting fibers tothe heart muscles, stimulating them to contract and relax in a regular sequence. When the heart muscles fail to receive the pacemakers signals, the heart ceases pumping blood ceases. Within a few minutes, the patient faints, andwithin a few more minutes, dies--unless the heart muscles can be stimulated to resume contracting. An artificial pacemaker is designed to help a damaged heart beat normally, programmed to send an electrical impulse to stimulate theheart muscle if it does not sense a normal heart beat within a specific amount of time. Dual-chamber pacemakers, the most common type, sense and pace activity in both the atrium (upper chamber) and ventricle (lower chamber). Single-pass pacemakers use only one lead and sense only one chamber, usually the ventricle. ...

Brevet US5228438 - Implantable pacemaker including means and method of terminating a pacemaker ... - Google Brevets
An atrial tracking dual-chamber pacemaker and method of use thereof for terminating a pacemaker-mediated tachycardia (PMT). The pacemaker includes means for determining whether the present heart rate exceeds a tachycardia reference rate, and if so, whether a PMT-indicating sequence of a tracked P-wave, including a retrograde P-wave followed by a V-pulse, occurs repetitiously for at least a predetermined number of cardiac cycles. The pacemaker includes means for measuring the interval between a P-wave and a V-pulse (PVI) and sets the PVI to 250 milliseconds when the measured value is less than 250 milliseconds. The pacemaker issues a PMT-terminating timed atrial pulse which is timed from a retrograde P-wave by a time equal to the PVI, plus a delay of about 25-100 milliseconds. In the event the atrial pulse fails to terminate the PMT, the process is repeated after a fixed number of cardiac cycles has occurred. An alternate embodiment includes determining a ventricular escape interval (VEI) which is equal
