Abstract

(2 figures) The effect of coronary artery ligation on electrophysiologic properties of cat ventricular muscle cells was studied. Depression of resting potential, action potential rate of rise and amplitude was observed in infarcted cells, 30 min to 5 days after ligation. Action potential duration was markedly shortened in acute stages (30-120 min) but gradually lengthened to above control by 48 h. Anatomic sequelae included oedema, loss of fibre striation and cellular necrosis.
