本文分析了70例充血型原发性心肌病的心电图、X线及超声心动图改变,结果如下: 1、心电图改变:70例均有心电图异常改变,其中QRS电轴不偏者占62.2％,电轴左偏及右偏者各占21.4％与15.8％。左室肥大或伴劳损的心电图改变占38％。ST—T改变为本病的常见(60％)心电图表现。部分患者有心律失常与传导阻滞。 2、X线改变:64例作了X线检查,除1例正常外,其他病例均有异常。62例有中一高度心脏增大(96.8％),仅2例心影大小正常。心影的形态以普大型占多数(64％)。此外,48例的X线检查中出现心肌张力低与心搏动弱的征象,表明心收缩功能降低是本病的主要病理生理异常。 3、超声心动图改变:64例检查结果:(1)心腔内径以左室增大为著,左室流出道增宽。(2)室间隔与左室后壁活动幅度低者占多数。(3)二尖瓣振幅低与二尖瓣CD段分离各占35例及47例。(4)主动脉活动幅度减低者32例。
This article analyzes 70 cases of congestive primary cardiomyopathy ECG, X-ray and echocardiographic changes, the results are as follows: 1, ECG changes: 70 cases were abnormal ECG changes, including QRS axial deviation who accounted for 62.2%, electricity Axis left and right deviation each accounted for 21.4% and 15.8%. Left ventricular hypertrophy or with strain of ECG changes accounted for 38%. ST-T changes to the common (60%) ECG manifestations of this disease. Some patients have arrhythmias and conduction block. 2, X-ray changes: 64 cases of X-ray examination, except one case of normal, other cases are abnormal. Sixty-two cases had moderate-to-high cardiac enlargement (96.8%), and only 2 cases had normal cardiac size. The shape of the heart shadow to the majority accounted for the majority (64%). In addition, 48 cases of X-ray examination showed low myocardial tension and signs of weak heartbeat, indicating that reduced systolic function is the main pathophysiology of the disease. 3, echocardiography changes: 64 cases of test results: (1) the diameter of the left ventricle to increase the left ventricular outflow tract widened. (2) ventricular septum and left ventricular posterior wall activity is low, the majority. (3) Low mitral amplitude and mitral segment CD segregation in 35 cases and 47 cases. (4) 32 cases of aortic decrease in activity.
