肥厚性心肌病心电图及动态心电图分析

目的观察肥厚性心肌病的心电图及动态心电图特点。方法对经超声心动图诊断确诊的88例肥厚性心肌病患者的心电图和动态心电图检查结果进行回顾性分析。结果最常见的心电图和动态心电图异常是ST-T改变，达73．86％～92．05％，其次是左心室肥大，达59．09％。动态心电图显示，肥厚型梗阻性与非梗阻性心肌病的频发室性期前收缩发生率分别为30％与2．g％，多形和成对的室性期前收缩、RonT现象发生率分别为45％与16．2％，短阵室性心动过速速发生率分别为40％与13．2％，两组间差异均有统计学意义（P〈0．05）。结论肥厚型心肌病心电图的主要表现为ST—T改变和左心室肥大，动态心电图有助于室性心律失常的诊断。

Features of Electrocardiogram and Dynamic Electrocardiogram in Patients with Hypertrophic Cardiomyopathy

Objective TO assess the features of electrocardiogram （EGG） and dynamic electrocardiogram （DCG） in patients with hypertrophic cardiomyopathy （HCM）. Methods ECG and DCG were analyzed retrospectively in 88 patients with HCM determined by echocardiography. Results ST-T change was the most common manifestation on ECG and DCG, up to 73.86%-92.05%, Left ventricular hypertrophy was the second, up to 59.09%. Frequent premature ventricular contraction, polymorphic and coupled ventricular premature contraction and R-on-T phenomenon, and unsustained ven- tricular tachycardia on DCG were significantly more frequent in obstructive HCM （30%, 45 % and 40%, respectively ） than in non-obstructive HCM（2.9%, 16.2% and 13.2%, respectively）（all P〈0.05）. Conclusion ST-T change and left ventricular hypertrophy are the main manifestations on ECG. DCG may be useful in diagnosis of ventricular arrhythmia in patients with HCM.
