Abstract
The present study reports on the epicardial spread of excitation during premature beats and during the initial stages of ventricular fibrillation, both of which were induced by single-test stimuli during regional ischemia or local hypothermia. Simultaneous recording of the activity at 48 epicardial sites on the right ventricle of dog hearts enabled us in some instances to demonstrate a circus movement.Keywords
