摘　　要：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ＮＹＨＡ１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（ＥＴＦＶ１）主要与左房大小和Ｅ峰相关，Ⅱ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 eltectrocardiography and a colour Dopper echocardiography werestudied, and by multiple stepwise regression analysis it was found that significant partial correlationsexist between PTFV1 and left atrial dimension as well 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 electrocardiographic indexes of abnormality of leftatriun combined with colour Dappler echocardiography may be more helpful to predict whether the latent left ventricular 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.
