Abstract: Objective To investigate the value of differential diagnosis of the configuration of QRS complex in lead aVR in patients with inferior wall myocardial infarction. Methods The configuration of QRS in 52 patients with pathological Q-wave both in lead Ⅲ and aVF were analyzed and the result of selective coronary arteriography was compared. Results 13 patients with the configuration of QRS in lead aVR appeared rS ( s), while 10 patients appeared QS(qs) and 29 Q(q)r,correlated with 12,4 and 0 patients with coronary arteriography showed stenosis or occlusion lesion in fight coronary artery or left circumflex artery (χ2 = 35.56, P = 0.000). Conclusions The con-figuration of QRS in lead aVR is helpful to differential diagnosis of the patients with pathological Q-wave both in lead Ⅲ and aVF. Patients with the configuration of QRS in lead aVR appear rS(s) could be diagnosed as old myocardial infarction,but excluded from old myocardial infarction while appearing Q(q)r.
