A 13 year old boy with an ostium primum atrial septal defect associated with alternating periods of sinus rhythm and ventricular rhythm is presented. Absence of auscultatory and phonocardiographic signs of an atrial septal defect made it impossible to diagnose the defect correctly during periods of ventricular rhythm.
本文报道了一名13岁男孩，患有原发孔型房间隔缺损，伴有窦性心律和室性心律交替发作。在室性心律发作期间，由于缺乏房间隔缺损的听诊和心音图体征，无法正确诊断该缺损。
