Four patients who had had a Fontan type of procedure for tricuspid atresia 23, 6, 6, and 11 months previously were investigated by ambulatory electrocardiographic recording and simultaneous recording of the jugular venous pressure and echocardiogram of the conduit or pulmonary valve. All had been considerably improved by the operation. In 1 patient episodes of supraventricular tachycardia were recorded but no rhythm disturbance was detected in the other 3. Pulmonary blood flow was shown to be pulsatile and atrial systole is an important factor in this. The conduit valve showed delayed opening and slow closure suggesting that its presence in the pulmonary circuit may be unnecessary.

对4例分别于23、6、6和11个月前接受了用于三尖瓣闭锁的Fontan手术的患者进行了动态心电图记录，并同步记录颈静脉压以及管道或肺动脉瓣的超声心动图。所有患者术后均有显著改善。1例患者记录到室上性心动过速发作，其他3例未检测到节律紊乱。肺血流呈搏动性，心房收缩是其中的一个重要因素。管道瓣膜显示开放延迟和关闭缓慢，提示其在肺循环中的存在可能是不必要的。
