Abstract
A case of atrial flutter is reported in which the hearing of "systoles en écho" led to the recognition in the phonocardiogram of a regularly alternating time interval between successive atrial sounds during the ventricular standstill caused by stimulation of the carotid sinus. A possible explanation is proposed involving alternating pathways of atrial excitation.
