The purpose of this study was to examine factors associated with the development of complete left bundle-branch block and the prognosis in a group of people not in hospital, who had no clinical evidence of ischaemic or valvular heart disease. Twenty-nine cases of left bundle-branch block without clinical evidence of ischaemic heart disease were noted in the Manitoba cohort of 3983 men under obs...

Four patients with paroxysmal supraventricular tachycardia have been studied using programmed electrical stimulation of the heart and intracardiae recordings. One patient had an atrioventricular (A-V) junctional tachycardia, possibly due to a rapidly discharging protected ectopic focus, and three patients had anomalous atrioventricular connections. The ECG recordings in all four patients showed...

Cardiac pacing through a transvenous catheter located in the right ventricle usually produces a pattern of left bundle branch block (LBBB). When right bundle branch block (RBBB) occurs during apparent right ventricular pacing, a complication (perforation or malposition of the catheter) has usually occurred. In the patient reported here, uncomplicated right ventricular transvenous pacing produce...
