this study was conducted to assess the incidence of abnormalities of ventricular depolarization (late potentials) in children with sinus rhythm after open heart surgery and their relation to spontaneous ventricular tachycardia. open heart surgery, particularly operations involving ventriculotomy, may predispose patients to the development of ventricular tachycardia (vt) or ventricular fibrillat...

Ventricular arrhythmias are common in patients with mitral valve prolapse. Ten patients with echocardiographically confirmed mitral valve prolapse and documented ventricular arrhythmias were included in this study. The aim was to assess the value of combined alpha- and beta-blockade (labetalol) compared with beta-blockade alone (propranolol) in the management of ventricular arrhythmias in these...

Introduction: Inhibition of renin angiotensin system represents an important approach in the management of cardiovascular diseases. The aim of this study was to explore the effects of pretreatment with non-hypotensive dose of angiotensin converting enzyme (ACE) inhibitor, ramiprilat and angiotensin type 1 (AT1) receptor blocker, losartan on myocardial infarct size and arrhythmias in a rat mo...

The importance of the central nervous system in the antiarrhythmic actions of diphenyhiydantoin and lidocaine was studied using arrhythmias induced by electrical stimulation of the posterior hypothalamus in cats. Hypothalamic stimulation resulted in cardiac arrhythmias mediated by the sympathetic nervous system. The arrhythmias occurred during stimulation, and recordings from cardiac sympatheti...

OBJECTIVE To study the determinants and outcome of arrhythmias after the Fontan type operation. DESIGN Retrospective analysis of data in patients operated on between 1972 and 1986 (follow up 5-19 years (mean 12 years)). PATIENTS All 60 patients undergoing a Fontan type procedure at the National Heart Hospital, London, during the study period (mean age (SD) 12.3 (6.8) years). RESULTS Posto...

AIM Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited cardiac disease predisposing to life-threatening arrhythmias. We aimed to determine the prevalence of arrhythmias and efficacy of beta-blocker treatment in mutation-positive family members diagnosed by cascade genetic screening. METHODS AND RESULTS Relatives of six unrelated CPVT patients were tested for the rele...
