Eight patients with prolapsed mitral valve syndrome, with a mid - or - end - diastolic click or murmur, underwent echocardiographic examination using ultrasound. Examination of the displacement of the valves by the "time motion" method showed all cases to have an abnormal recoil; in 6 cases this occurred in mid or late systole, and in two from the beginning of systole. The recorded amplitude of the pathological displacement, which gives the systolic tracings a domed appearance, and the consistancy with which it could be recorded (irrespective of the incidence of the ultrasonic waves), seem to afford a method for evaluating the degree of prolapse which, in most cases, involves both the valves. The authors compare their results with those which have already appeared in the literature, and emphasise the very real contribution which echocardiography can make in the diagnosis and assessment of the prolapsed mitral valve syndrome.
8例患有二尖瓣脱垂综合征、伴有舒张中期或晚期喀喇音或杂音的患者接受了超声心动图检查。通过“时间-运动”方法对瓣膜移位进行检查显示，所有病例均有异常回弹；6例发生在收缩中期或晚期，2例从收缩期开始就出现。记录到的病理性移位幅度使收缩期描记呈圆顶状，且能够一致地记录下来（与超声波的发生率无关），这似乎提供了一种评估脱垂程度的方法，在大多数情况下，两个瓣膜均受累。作者将他们的结果与文献中已发表的结果进行了比较，并强调了超声心动图在二尖瓣脱垂综合征的诊断和评估中所能做出的切实贡献。
