Instability in action potential morphology underlies phase 2 reentry: a mathematical modeling study.

Abstract

BACKGROUND Phase 2 reentry occurs when electrotonic current propagates from sites of normal notch-and-dome action potentials (APs) to loss-of-dome abbreviated AP sites, causing abnormal reexcitation. The existence of two neighboring regions exhibiting these two different AP morphologies is believed to be sufficient for local reexcitation and development of… (More)
