Supernormal responses to premature stimulation in Ca-dependent action potentials.

H Iinuma, K Kato.   

Abstract

The responses of Ca-dependent action potentials to premature stimulation were studied in the isolated canine ventricular muscle. When very premature stimuli were applied, supernormally augmented responses with propagation occurred, while responses with long preceding intervals were small and not conducted.
