An infant with cyanotic congenital heart disease underwent M mode echocardiography, cardiac catheterisation and angiography. A diagnosis of pulmonary atresia with intact ventricular septum was made. Echocardiography showed an average sized right ventricle with tricuspid valve thickening, as previously described in this condition. In the pulmonary incidence, a giant A wave, occuring after the P wave of the surface ECG, without a systolic valvular opening, was recorded. This probably corresponded to the motion of the diaphragm separating the pulmonary infundibulum from the true pulmonary artery. The possibility of recording the giant A wave of the fibrous diaphragm should be recalled in patients with pulmonary atresia with intact ventricular septum.
一名患有青紫型先天性心脏病的婴儿接受了M型超声心动图、心导管检查和血管造影。诊断为室间隔完整的肺动脉闭锁。超声心动图显示右心室大小正常，三尖瓣增厚，如之前在这种情况下所描述的。在肺动脉发生率方面，记录到一个巨大的A波，出现在体表心电图的P波之后，且无收缩期瓣膜开放。这可能对应于将肺动脉漏斗部与真正的肺动脉分隔开的膈肌运动。对于室间隔完整的肺动脉闭锁患者，应记住记录纤维性膈肌巨大A波的可能性。
