This report describes the case of a patient with a supraventricular tachycardia with a
ventricular rate of 109/min and no visible P waves in the electrocardiogram. 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 repolarisation in the action potential.
This report emphasises the fact that the phenomenon of alternans occurs in man, as in the
experimental animal, at a cellular level.
