Abstract
The case of a patient with a supraventricular tachycardia with a ventricular rate of 109/min and no visible P waves in the ECG was described. The recording of the monophasic action potential of the right atrium disclosed an atrial tachycardia with a rate of 218/min. There was an alternans of the phase 2 of repolarization in the action potential. The fact that the phenomenon of alternans occurs in man, as in the experimental animal, at a cellular level was emphasized.This publication has 16 references indexed in Scilit:
