心电图u波异常对老年冠心病诊断的临床意义

Clinical Help of Abnormal Electrocardiogram U Wave for Senile Coronary Heart Disease

u波倒置可见于心肌梗塞、心绞痛、左室肥厚等。本文对267例冠心病患者常规心电图检查中,对其u波改变进行了观察,其结果显示u波消失者107例,u波倒置者6例,u波异常检出率总共为42.3％。在冠心病不同类型中,以心肌梗塞,心力衰竭型,慢性冠脉供血不足时检出率最高。因此认为u波的观察可作为冠心病一种常用的无创性的检查方法之一。

Inversion of U wave can be found in the diseases of heart infarction,angina pectoris and left ventricular hypertrophy, etc. Among the 267 cases of routine electrocardiogram examination of coonary heart disease, this aricle observes the alteration of the U wave. the detectable rate of abnormal U wave is 42. 3% in total. Of the differdent types of coronary heart disease,heart infarction,heart failure and chronic coronary artery’s blood supply deficiency are among the highest detectabl rate. It suggests that the observation of U wave be used as one of the noninvasive examinations of coronart heart disese.
