Transvenous electrodes were placed in the right atrium and ventricle of 50 patients with heart disease and arrhythmias. The ventricles were paced at several rates, each in excess of the sino-atrial rate. An atrial electrogram and surface electrocardiogram were recorded simultaneously in each patient; utilizing strict criteria, the incidence with which 1:1(More)
Studies have shown that in patients with paroxysmal supraventricular tachycardia (SVT), spontaneous or stimulated atrial premature depolarizations (APD) falling within a specific portion of the relative refractory period of the atrioventricular (A-V) conduction system initiate SVT. The present study was designed to determine whether the A-V nodal conduction(More)
P synchronous pacing has long been identified as advantageous for patients with atrioventricular conduction defects and intact sinus node function. Prior endocavitary systems have been infrequently employed, because of unreliable P wave sensing from standard ring electrodes in the atrium or the requirement for a second atrial sensing lead. A single(More)
Pediatric polymyositis may be an entity distinct from dermatomyositis. Chronic polymyositis can occur in childhood and, as in adults, may be associated with arrhythmias. Microscopical involvement of the myocardium and pericardium in dermatomyositis is probably far more common than suspected on clinical grounds. Cardiac evaluation is suggested for all(More)
Fifteen acute myocardial infarction patients (only one of whom had evidence of significant renal dysfunction) received a constant-rate intravenous infusion of procainamide at one rate for a least 24 hours. Steady-state plasma levels achieved during these infusions were used to calculate total body clearance (C/B). Linear regression analysis of C/B versus a(More)
