Ventricular late potentials detected by signal averaging have a high predictive value for the origin of malignant ventricular tachyarrhythmias in patients with coronary artery disease. We examined 35 male sportsmen aged from 22 to 33 years. Clinical examination, ECG at rest, echocardiography and signal averaging were performed. In nine of the 35 sportsmen (26%) ventricular late potentials were detected. In a control group of 20 nonsportsmen none had late potentials. The nine sportsmen with late potentials all had electrocardiographical and echocardiographical signs of left-ventricular hypertrophy. Of the 26 sportsmen without ventricular late potentials five had left-ventricular hypertrophy. Ventricular late potentials are not rare in sportsmen. They seem always to appear together with left-ventricular hypertrophy.
通过信号平均检测到的心室晚电位对冠心病患者恶性室性心律失常的起源具有较高的预测价值。我们检查了35名年龄在22至33岁之间的男性运动员。进行了临床检查、静息心电图、超声心动图和信号平均检测。在35名运动员中，有9名（26%）检测到心室晚电位。在20名非运动员的对照组中，无人有晚电位。9名有晚电位的运动员均有左心室肥厚的心电图和超声心动图表现。在26名无心室晚电位的运动员中，有5名有左心室肥厚。心室晚电位在运动员中并不罕见。它们似乎总是与左心室肥厚同时出现。
