摘要
目的探讨下壁心肌梗死时心电图aVR导联QRS波群形态的改变。方法分析89例急性下壁心肌梗死患者心梗前、后以及1年后的心电图和100例经冠状动脉造影证实的无冠心病患者的心电图,分析aVR导联QRS波群形态的变化。结果急性下壁心肌梗死前和无冠心病患者的心电图aVR导联QRS波群多呈q(Q)r型(89.2%),少数呈QS型(10.8%);下壁心肌梗死后及1年后心电图aVR导联QRS波群多呈rs(S)型(86.21%),少数呈QS型(12.77%),极少数呈Qr型(1.02%)。结论下壁心肌梗死后心电图aVR导联QRS波群多呈r(sS)型。
Objective To observe the variation of QRS wave in lead aVR in inferior myocardial infarction patients. Methods To analyze the variation of QRS wave in lead aVR in 89 patients with inferior myocardial infarction pre-and poststage of myocardial infarction and 1 year later,in addition to those patients without coronary heart disease detected by coronary visualization. Results QRS always presents as q（Q）r（89.2%） in those patients before infarction and those patients without coronary heart disease,while QS was seen in few subjects. Besides QRS always presents as rs （S） （86.21%） in those patients post-infarction and 1 year later,and some QS （12.77%） was seen as well as few Qr （1.02%）. Conclusions rs （S） frequently presents in lead aVR in ECG of patients with inferior myocardial infarction.
