老年异常Q波心电图改变148例

ECG changes of The elderly with abnormal Q wave:A clinical analysis of 148 cases

目的观察老年人异常Q波心电图改变及其临床意义。方法选择年龄≥60岁的老年人异常Q波148例,均经心电图、心肌酶谱、超声心动图检查及结合临床明确诊断。结果非梗死性Q波组122例(82.4%),其中位置性Q波95例(77.9%),异常Q波19例(15.5%),酷似急性心肌梗死8例(6.6%)。Q波心肌梗死组26例(17.6%),其中ST-T抬高动态改变符合急性心肌梗死18例(69.2%);T波倒置符合陈旧性心肌梗死8例(30.8%)。结论老年异常Q波应进行心电图动态观察、实验室检查及结合临床病史全面综合分析,除外非梗死性Q波,应提示Q波心肌梗死的诊断。

Objective To explore the elderly abnormal Q wave ECG changes and clinical significance. Methods A total of 148 cases of elderly people aged 360 years with abnormal Q waves by ECG were selected and confirmed by electrocar- diogram, myocardial enzymes, echocardiography and clinical diagnosis. Results Non-Q-wave infarction group 122 （82.4%）, the location of the Q wave which 95 cases （77.9%）, abnormal Q wave in 19 cases （15.5%）, like acute myocardial infarction in 8 cases （6.6%）. Q-wave myocardial infarction, 26 cases （17.6%）, ST-T elevation in which the dynamic changes consistent with acute myocardial infarction 18 cases （69.2%）, T-wave inversion myocardial infarction in 8 cases （30.8%）. Conclusion Aged ECG abnormal Q waves must be dynamic observation, In conjunction with laboratory tests and comprehensive analy- sis of the clinical history, except for non-Q wave infarction, should prompt the diagnosis of Q-wave myocardial infarction.
