Abstract

Our study provides a reasonably detailed "repolarization map" of the ventricular surface in the dog heart. The approximately constant repolarization slope of all MAP's on the surface supports the validity of the assumption that the sequence of ventricular repolarization can be derived from the sequence of refractoriness. Our results agree with the studies of functional refractory periods and show that the duration of recovery tends to shorten during the course of activation. This sequence is consistent with the positive ventricular gradient in the electrocardiogram.
