有关肥厚了的左心室收缩功能,根据实验室和临床资料,一些作者认为心肌肥厚导致心肌收缩性降低。而另一些作者认为在无循环机能不全的临床特征时收缩性正常或在心电图上出现《负荷过重》时,其收缩性降低。本文将不同病因的高血压患者的左心室中心血流动力学,心脏形态和收缩功能与左心室肥厚的心电图指标作了比较研 About hypertrophy of left ventricular systolic function, according to laboratory and clinical data, some authors believe that myocardial hypertrophy leads to decreased myocardial contractility. Others, however, believe that contractility decreases when contractile is normal in the absence of clinical features of circulatory insufficiency or “overload” occurs on the electrocardiogram. In this paper, different causes of hypertension in patients with left ventricular central hemodynamics, cardiac function and systolic function compared with left ventricular hypertrophy ECG
