摘　　要：目的　分析临床心电图 (ECG)出现异常Q波而核素心肌显像正常的原因。方法　 6 9例患者分别行ECG和2 0 1 Tl心肌显像。其中男 5 2例 ,女 17例 ,4 5岁以下 2 8例。结果　 2 5例ECG表现为前间壁心肌梗死 ,33例表现为下壁心肌梗死 ,5例表现为前间壁 +下壁心肌梗死 ,4例表现为侧壁心肌梗死 ,2例表现为正后壁心肌梗死 ;误诊为前间壁或下壁心肌梗死共 6 0例 ,占 87%。经心脏超声、ECG等检查 ,6 9例中 9例为心室内传导障碍 ,7例为扩张型心肌病 ,5例为肥厚型心肌病 ,2例为风湿性心脏病主动脉瓣关闭不全 ,共 2 3例 ,占 33 3% ,其余各种检查未见明显异常。结论　依靠ECG诊断陈旧性心肌梗死应慎重 ;核素心肌断层显像应为诊断心肌梗死的常规检查方法。Objective To analyse the cause of abnormal Q wave ECG but with normal 201Tl myocardial imaging. Methods 69 patients both studied with ECG and 201Tl myocardial imaging. Results 60 of 69 cases, 87% have abnormal Q wave. 23 of 69 cases, 33.3%, include 9 intraventricular conductional block, 7 dilated cardiomyopathy, 5 hypertrophic cardiomyopathy, 2 aortic regurgitation. All patients have normal results in 201Tl myocardial imaging. Conclusions The diagnosis of old myocardial infarction by ECG must be w...
