Determinants of postrepolarization refractoriness in depressed mammalian ventricular muscle.

Abstract

Functional determinants of postrepolarization refractoriness were studied with microelectrodes in isolated cat and dog ventricular muscle preparations mounted in a three-chambered bath. Frequency-dependent conduction delay and block were readily manifested when the central segment (1 mm) was superfused with high potassium (20-30 mM) Tyrode's solution… (More)
