摘要
本文202例冠心病患者中静息12导心电图上出现u波倒置的共37例(18.3%)。u波倒置的出现与冠心病心绞痛发作密切相关,主要表现在左心前V_3～V_5导联。结果表明u波倒置的出现主要与前壁部位的心肌缺血有关。
Inversion of U wave of the resting 12-lead electrocardiogram was found in 37 of 202 patients with CHD (18.3%). Among 37 patients the occurrence of inversion of U wave in unstable angina pectoris was most common (56.3%) and that in patients with myocardial infarction was less (35～36%). Among the 42 patients with myocardial infarction, U wave inversion was mainly found in those with anterior subendocardial and anteroseptal myocardial infarction. It was rarely found in inferior myocardial infarction. The occurrence of U wave inversion usually coincided with the attack of angina pectoris. U wave inversion was commonly present in left anterior precardial leads V3 through V5. The results demonstrate: that the appearance of U wave inversion is mainly related to the ischemia of anterior myocardialarea.
