Among 1,519 patients undergoing diagnostic cardiac catheterization over a 2-year period, angiographically unequivocal mitral valve prolapse was identified in 79 cases (5.2%). Mitral valve prolapse was clinically unsuspected in 30 of these 79 patients

Electrophysiologic evidence for dual pathways of conduction through the A-V node is presented in three patients without history of supraventricular tachycardia. In case 1, abrupt spontaneous changes in the PR interval from 0.17 to 0.42 second were se

In order to correlate the antiarrhythmic and electrophysiological effects of disopyramide phosphate during acute myocardial ischemia, we performed experiments in 17 mongrel dogs. Refractory periods obtained by the extrastimulus method and conduction

The increasing use of changes in the S-T segment of local epicardial electrograms to quantitate myocardial infarct size has led to the need for a better understanding of this method. Accordingly, we studied the local electrographic, tension and bioch

This study was designed to determine whether treadmill exercise testing could identify patients with critical coronary lesions. Critical lesions were defined as obstruction of the left main coronary artery or concomitant narrowing of the left anterio

The significance of hypotension developing during treadmill exercise testing was evaluated and correlated with the findings at cardiac catheterization in two groups of patients. Twenty-five patients (Group I) had a fall in systolic pressure during ex

The effect of ventricular premature contractions on atrioventricular (A–V) conduction of the following sinus beat was studied in 25 patients with use of His bundle electrography. Facilitation of A–V conduction (shortening of the A–H interval) i
