超声心动图对高血压病左室结构变化及其功能测定的应用研究和评价

Analytic Study and Assement for Detection of Left Ventricular Hypertrophy and Its Function in Essential Hyprtension by Eehocardiography

本文应用超声心动图对51例高血压病患者及27例健康人进行了检测。根据其左室结构和舒缩功能的各项参数变化进行分析,证实超声心动图能早期发现其异常,对左室肥厚的诊断较心电图为优;多普勒超声对舒缩功能的测定效果与M型超声相似,并发现左室舒张功能出现异常较收缩功能为早,且可见左室正常患者的收缩作功可以超常。本文还对高血压病左室结构变化、舒缩功能变异特征及有关参数间的内在联系进行了分析探讨。

Fifty-one cases of essential hypertension and 27 normotensve adult were detected by echocardiography (ME, BE and PDE). Following analysis through the changes of various data of left ventricuar stcte and its systolie and diastolic fnction proved that the echoa diogaphy ca dsover the abnormalities in early stage of essential hypertension and it is much better to diagnose the left ventricular hypertrophy than electrocardiography. Echocardiography including PDE and ME showes the same excellent value for clinical application to detect the ventricular functions. It is found that the abnormality of diastolic fnction reveals itself earlier than the sstolie funion.It is also found that the systolie work of patients with noml left ventricle can be supernormal. The changes of left veatricular structure and the characteristic variatios of systo-diastolic function in essential hypertension and its interrelationship of correlated data were also analysed and discussed.
