作者将慢性重度主动脉瓣返流(AR)病人的心电图表现同左室功能的超声参数进行比较分析如下。对象与方法:平均40(16～64)岁的40(男30,女10)例慢性重度AR病人,其中24例经血流动力学测定,16例经心脏多普勒血流标测,证实为重度返流(3+～4+/4)。心电图和超声心动图均在使用洋地黄之前记录。心电图(ECG)分析:左室肥厚时12导联QRS总振幅>175mm(10mm=1 mV)。任何心前导联T波>1mV为T波高电压。V_2～V_(?),导联上或者QRS电轴对应的侧壁或下壁肢导联上,出现双相T波或者不对称倒置T波,伴有ST段等电位线或压低>1mm者,定为左室劳损。轻度ST段
The authors compare the ECG findings of left ventricular function with those of patients with chronic severe aortic regurgitation (AR) in the following analysis. Subjects and Methods: A total of 40 (16 males, 30 males and 10 females) patients with chronic severe AR were enrolled in this study. Among them, 24 patients were diagnosed as hemodynamics by flow cytometry and 16 by Doppler echocardiography Reflux (3 + ~ 4 + / 4). ECG and echocardiography were recorded before using digitalis. ECG analysis: 12-lead QRS total amplitude> 175 mm (10 mm = 1 mV) at left ventricular hypertrophy. Any heart T wave T> 1mV for T wave high voltage. V_2 ~ V_ (?), Lead or QRS axis corresponding to the side wall or lower limb leads appear on the biphasic T wave or asymmetric inverted T wave, with ST-segment isoelectric line or depression> 1mm , Set for left ventricular strain. Mild ST segment
