应用二维超声心动图在连续1134倒受检者中,检出左室假腱索93例,检出率为8.2％,其中67例随访观察了平均3.8年。结果发现绝大多数假腱索位于左室流出道和心尖部。临床表现和24小时动态心电图显示心尖部收缩期杂音和室性心律失常极为常见,存病程中有猝死的可能性。
Ninety-three cases of left-ventricular false tendons were detected by two-dimensional echocardiography in 1134 inverted subjects, with a detection rate of 8.2%. 67 of them were followed up for an average of 3.8 years. The results found that the vast majority of false tendons in the left ventricular outflow tract and apex. Clinical manifestations and 24-hour ambulatory ECG showed apical systolic murmur and ventricular arrhythmias are extremely common, there is the possibility of sudden death in the course of disease.
