目的:探讨急性心肌梗死(AMI)U波倒置的临床意义。方法:对150例AMI患者中21例有U波倒置的进行分析。结果:有U波倒置患者心绞痛的发生率为76.2%(16/21例),高于无U波倒置者的33.3%(43/129例)(P<0.01)。U波倒置常提示存在左前降支病变,本组5例U波倒置冠状动脉造影均有左前降支病变(100%),无U波倒置19例行冠状动脉造影11例(57.9%)有左前降支病变(P=0.1028)。结论:以上结果提示,U波倒置对诊断冠心病可能比T波异常更具有特异性。
Objective: To investigate the clinical significance of U wave inversion in acute myocardial infarction (AMI). Methods: UW wave inversion was performed in 21 of 150 AMI patients. Results: The incidence of angina pectoris in U wave inversion patients was 76.2% (16/21 cases), which was higher than 33.3% (43/129 cases) without U wave inversion (P <0.01). U-wave inversion often prompted the presence of left anterior descending coronary artery disease, the group of 5 patients with U-wave inversion coronary angiography have left anterior descending coronary artery disease (100%), no U-wave inversion 19 routine coronary angiography in 11 cases (57.9% Dilated lesions (P = 0.1028). Conclusion: The above results suggest that U wave inversion may be more specific than T wave in the diagnosis of coronary heart disease.
