摘要
为探讨原发性高血压 (以下简称高血压 )患者左室收缩时间间期的变化及临床意义 ,观察 3 5 7例初诊高血压患者以及 1 0 0例正常人的左室射血分数 (LVEF)、射血时间 (LVET)、射血前期 (PEP) ,并对以上指标分别进行方差分析。结果 :高血压患者的LVET、PEP、PEP/LVET与正常组比较有显著性差异 (P <0 .0 5 ) ;LVEF与正常组比较无显著性差异。结果提示 :收缩时间间期可敏感的反映左室后负荷的升高。
The aim of this study was to determine the clinical application of echocardiography in assessing the change of left ventricular systolic time interval in patients with hypertension. The study measured pre-ejection period (PEP), left ventricular ejection time (LVET), PEP/LVET and left ventricular ejection fraction (LVEF) in patients with hypertension and normal subjects by echocardiography, and compared the data with the normal subjects using of analysis of t test. In patients with hypertension, systolic time interval is the sensitive index in discriminating the increase of left ventricular afterload.
