1/45. Asymptomatic form of brugada syndrome.We describe a patient with the asymptomatic form of brugada syndrome. His electrographical, electropharmacological, and electrophysiological characteristics were similar to those reported in patients with the symptomatic form of brugada syndrome. We believe that he has the same arrhythmogenic substrate as that of patients with brugada syndrome. The fact that he had no episode of spontaneous ventricular fibrillation might be explained by his absence of the triggering factors.- - - - - - - - - - ranking = 1keywords = arrhythmogenic (Clic here for more details about this article) |
2/45. syncope and inducible ventricular fibrillation in a woman with hemochromatosis.BACKGROUND: hemochromatosis has been associated with atrial tachyarrhythmias and congestive heart failure as a consequence of dilated or restrictive cardiomyopathy. Inducible ventricular fibrillation has not been previously described.methods AND RESULTS: An electrophysiologic study was conducted in a woman after two episodes of syncope. Polymorphic ventricular tachycardia (PMVT) and ventricular fibrillation (VF) were induced with ventricular programmed stimulation. magnetic resonance imaging demonstrated signal loss in the liver consistent with hemochromatosis, but normal cardiac size and function. Hematologic studies supported a diagnosis of hemochromatosis.CONCLUSION: Cardiac hemochromatosis may be associated with serious ventricular arrhythmias.- - - - - - - - - - ranking = 0.009763952511806keywords = cardiomyopathy (Clic here for more details about this article) |
3/45. Ventricular tachycardia in an adolescent with arrhythmogenic right ventricular dysplasia.We report the case of an adolescent boy with exertional syncope and ventricular tachycardia caused by arrhythmogenic right ventricular dysplasia. diagnosis was determined by transthoracic echocardiography and definitive management with an automatic internal cardiac defibrillator. Emergency physicians must be aware of this serious but treatable cause of adolescent exertional syncope.- - - - - - - - - - ranking = 31.706402390996keywords = ventricular dysplasia, right ventricular dysplasia, arrhythmogenic right ventricular dysplasia, arrhythmogenic, arrhythmogenic right, dysplasia (Clic here for more details about this article) |
4/45. cocaine-induced bradyarrhythmia: an unsuspected cause of syncope.cocaine use is associated with adverse events in nearly every organ system. Cardiovascular complications include hemorrhagic and ischemic stroke, aortic dissection, cardiomyopathy, accelerated coronary artery disease, myocardial infarction, and sudden cardiac death. syncope may be the presenting symptom in these conditions. However, cocaine-induced bradyarrhythmias have been scarcely mentioned. As this case exemplifies, clinicians should be aware of this association when they evaluate syncope, especially in young patients.- - - - - - - - - - ranking = 0.009763952511806keywords = cardiomyopathy (Clic here for more details about this article) |
5/45. Right ventricular cardiomyopathy showing right bundle branch block and right precordial ST segment elevation.A 73-year-old man who had a family history of sudden death, experienced syncope. His electrocardiogram (ECG) presented right bundle branch block and right precordial ST segment elevation which are findings identical with those in brugada syndrome. The cardiac MRI showed right ventricular mild dilatation, and endomyocardial biopsy revealed fatty replacement of myocardial fibers. Though no ventricular tachyarrhythmias were induced during an electrophysiologic test, the effects on ECG of antiarrhythmic agents and autonomic modulations were similar to those in brugada syndrome. This case may suggest the relationship between brugada syndrome and right ventricular cardiomyopathy.- - - - - - - - - - ranking = 0.04881976255903keywords = cardiomyopathy (Clic here for more details about this article) |
6/45. arrhythmogenic right ventricular dysplasia. An illustrated review highlighting developments in the diagnosis and management of this potentially fatal condition.arrhythmogenic right ventricular dysplasia is an inherited, progressive condition. Characterised by fatty infiltration of the right ventricle, it frequently results in life threatening cardiac arrhythmias, and is one of the important causes of sudden cardiac death in the young. There are characteristic electrocardiographic and echocardiographic features that all physicians need to be aware of if we are to reduce these occurrences of premature death. diagnosis with magnetic resonance imaging is discussed along with current treatment options.- - - - - - - - - - ranking = 19.199759490745keywords = ventricular dysplasia, right ventricular dysplasia, dysplasia (Clic here for more details about this article) |
7/45. arrhythmogenic right ventricular dysplasia: an uncommon cause of syncope in a young male.arrhythmogenic right ventricular dysplasia (ARVD) is a relatively rare disease first described in 1977. It is characterized by replacement of the right ventricle (RV) by fat or fibrous tissue. patients often present with symptomatic ventricular tachycardia (VT) and the risk of sudden death is approximately 2.5% per year. Physical exam is often unremarkable. To date, the best diagnostic test is the MRI, however, electrocardiographic and echocardiographic data are useful. Treatment can be with beta blockers if a medical approach is desired. Multiple surgical options are available. No long-term studies are available to guide therapy; thus each case should be dealt with on its merits. This article describes the case of a 41-year-old male who had been asymptomatic until he presented with syncope. An extensive work up was undertaken and ARVD was diagnosed by MRI.- - - - - - - - - - ranking = 19.199759490745keywords = ventricular dysplasia, right ventricular dysplasia, dysplasia (Clic here for more details about this article) |
8/45. Rare association of hypertrophic cardiomyopathy and complete atrioventricular block with prompt disappearance of outflow gradient after DDD pacing.Although arrhythmias are common in hypertrophic cardiomyopathy (HCM), complete atrioventricular (AV) block is very unusual. A 27-year-old female presented with a recent history of syncope and exercise intolerance. ECG demonstrated complete AV block. Two-dimensional Doppler echocardiography revealed HCM with a 60 mmHg left ventricular outflow tract (LVOT) gradient. A temporary transvenous ventricular pacemaker was inserted urgently, and subsequently replaced by a permanent DDD pacemaker. All symptoms were eliminated. This symptomatic improvement was associated with complete disappearance of LVOT gradient at the time of implantation. No gradient was observed during early follow-up and at 6 months after DDD pacemaker implantation.- - - - - - - - - - ranking = 0.04881976255903keywords = cardiomyopathy (Clic here for more details about this article) |
9/45. Pulmonary vein orifice isolation for eliminating paroxysmal atrial fibrillation after ICD implantation.We treated a patient with dilated cardiomyopathy (DCM) and sustained ventricular tachycardia by an implantable cardioverter defibrillator (ICD). He then suffered from inappropriate ICD shocks triggered by paroxysmal atrial fibrillation (AF). We successfully performed pulmonary vein orifice isolation to eliminate paroxysmal AF. The pulmonary vein orifice isolation was a simple and useful procedure for eliminating paroxysmal AF in patient with decreased left ventricular (LV) function after ICD implantation.- - - - - - - - - - ranking = 0.009763952511806keywords = cardiomyopathy (Clic here for more details about this article) |
10/45. Hypoglycemic syncope induced by a combination of cibenzoline and angiotensin converting enzyme inhibitor.A 65-year-old Japanese woman with dilated cardiomyopathy, hypothyroidism and refractory sustained ventricular tachycardia experienced a near-death hypoglycemic syncope. The attack seemed to be induced by a high level of serum insulin, probably due to cibenzoline and by concomitant use of an angiotensin converting enzyme inhibitor (ACEI). Additionally, decreased food intake because of a severe toothache may have contributed to the deterioration of her condition. This case warns cardiologists that a combined cibenzoline and ACEI therapy can provoke serious adverse effects such as hypoglycemic syncope in the elderly. Therefore, the possibility of a hypoglycemic attack associated with these drugs should be explained to patients who are in poor condition.- - - - - - - - - - ranking = 0.009763952511806keywords = cardiomyopathy (Clic here for more details about this article) |
