OBJECTIVE To investigate the feasibility of performing electrophysiological studies at a district general hospital and to evaluate the importance of such studies in the management of patients with suspected arrhythmias. DESIGN Retrospective study of patients having had electrophysiological studies during a three year period. SETTING District general hospital. SUBJECTS 93 patients (50 men,...

Pregnancy can precipitate cardiac arrhythmias not previously present in seemingly well individuals. Risk of arrhythmias is relatively higher during labor and delivery. Potential factors that can promote arrhythmias in pregnancy and during labor and delivery include the direct cardiac electrophysiological effects of hormones, changes in autonomic tone, hemodynamic perturbations, hypokalemia of p...

Ventricular extrasystole originating from the right ventricular outflow tract or the left ventricular outflow tract are the most commonly encountered ventricular arrhythmias recorded in ostensibly healthy individuals with no evidence of heart disease. These ventricular arrhythmias have a distinctive electrocardiographic morphology. The morphology is so distinctive that it is common practice to ...
