In three patients with hypertrophic cardiomyopathy, a late systolic click following mid systolic murmur was recognized. M-mode and two-dimensional echocardiography showed the presence of systolic anterior motion of the chordae tendineae in all cases. Phonoechocardiographic studies showed that the time of the click always coincided with the endpoint of mild anterior motion of the chordae tendineae. The click was considered to be a chordal snap.
在3例肥厚型心肌病患者中，可识别出收缩中期杂音后出现的收缩晚期喀喇音。M型和二维超声心动图显示所有病例均存在腱索收缩期前向运动。心音超声研究表明，喀喇音的时间总是与腱索轻度前向运动的终点相一致。该喀喇音被认为是腱索卡嗒音。
