摘　　要：目的探讨急性前壁心肌梗死时胸前导联U波倒置的意义。方法对67例首次发病24h内，无对心电图U波有影响并发症及其它疾病者入院时的心电图进行分析，并测定其核素心肌梗死面积和核素心功能。结果67例患者U波倒置组25例，无U波倒置组42例；U波倒置组核素心梗面积为（33±7）％，左室射血分数（LVEF）（44±4）％，前1／3充盈分数（1／3FF）（0.32±0．07）％，病理性Q波导联数（2．1±1．0）；而无U波倒置组核素心梗面积为（49±9）％，LVEF（35±6）％，1／3FF（0．21±0．09）％，病理性Q波导联数（3．1±1．2）；两者比较差异有显著性（P＜0．05）。结论急性前壁心肌梗死患者入院时胸前导联U波倒置的出现预示心肌梗死面积相对较小，其LVEF亦可能＞40％。Objective To clarify the relationship between negative U waves in the precordial leads and nuclide myocardial infarction size. Method 67 patients with first anterior wall myocardial infarction (AMI) were Observed (≤24hour). Results There were negative U waves in 25 cases and there were not in 42, and in the former the infaret was smaller and LVEF bigger. Conclusion Negative U waves in the precordial leads on admission in patients with anterior wall AMI show their myocardial infarction size smaller and cardiac function better.[
