摘要
本文通过心阻抗图，心音图及心电图法对高血压患者的心房收缩时间间期（ＡＳＴＩ）进行了研究。结果显示，与对照组比较，高血压患者的心房射血前间期（ＡＰＥＰ）明显缩短，心房射血时间（ＡＥＴ）显著延长，ＡＰＥＰ／ＡＥＴ比值显著降低（Ｐ均＜０．０１）。这些指标的变化与高血压导致的左室肌肥厚的程度均呈显著相关关系。提示高血压导致的左室肌厚度改变是使其顺应性下降的重要因素。ＡＳＴＩ可作为反映这一顺应性变化的指标。
Atrial systolic time intervals(ASTI )measured by cardiac impedance ple-thysmogram,phonocardiogram and electrocardiogram were studied in control and hyperten-sive subjects.The results showed that a shorter atrial pre-ejection period( APEP),a longeratrial ejection time(AET)and a smaller ratio of APEP/AET in hypertensive patientswhen compared with that of the control(all P<0.01),The changes of the measurementswere highly correlative with thickness of the left ventricular wall.The results suggestedthat the alteration of left ventricular wall thickness induced by hypertension play an im-portent role in the decline of ventricular diastolic compliance and ASTI might be takenas a parameter for detecting the compliance change.
