Abstract
The time intervals between the onset of ventricular depolarization and of right ventricular contraction were studied in 36 patients, by means of cardiac catheterization, and were correlated with their vectorcardiograms and electrocardiograms. The onset of right ventricular contraction was delayed in six subjects without heart disease but with the electrocardiographic picture of right bundle-branch block. The onset of right ventricular contraction was found to be normal in 10 of 15 patients with right ventricular hypertrophy with the electrocardiographic picture of right bundle branch block. This indicates that this electrocardiographic configuration is not necessarily accompanied by delayed right ventricular contraction.
