采用彩色多普勒超声心动图描记术和常规心电图研究48例心功能NYHA I级的高血压和冠心病患者,经多因素逐步回归分析,发现常规心电图V1导联P波终末电势(PTFV1)主要与左房大小和E峰相关,:导联P波时限与P-R段比值(Macruz)指数则是反映A峰和A/E改变的敏感指标.两方法联用对早期检测是否存在潜隐的左室舒张功能不全有价值.

Forty-eight patients with essential hypertension or coronary disease in cardiac function NYHA class I underwent a routine electrocardiography and a cotour Dopper echocardiography were studied,and by multiple stepwise regression analysis irwas found that significant partial correlations exist between PTFVl and left atrial dimensionas wee as E peak,Macruz index and A peak.Macruz index≥1.6 gave a sensitivity of 71%VS accuracy 64% for A peak increase(>70 cm/s),of 61% vs 58% for A/E>1 respectively,.These results suggest that electrocardiographlic indexes of abnormality of left atriun combined with Colour Doppler echocardiograpby may be more helpful to predict wkether the latent left ventricutar diastolic dysfunction or decrease of diastolic reserve was present or absent in patients with essential hypertension or coronary artery disease in normal clinical cardiac function.
