Significance of ST-segment deviation in lead aVR for prediction of culprit artery and infarct size in acute inferior wall ST-elevation myocardial infarction

AbstractBackgroundIn patients with acute ST-segment elevation myocardial infarction identification of the culprit artery either due to right coronary artery or left circumflex artery was studied. The electrocardiogram can help in earlier risk stratification and better guidance of therapy for reperfusion.Patients and methods50 patients with acute inferior myocardial infarction were divided into two groups. Group A: patients with ST segment depression in lead aVR⩾1mv. Group B: patients with isoelectric ST segment or with ST segment depression in lead aVR
