The severity of ST segment elevation in acute inferior myocardial infarction: Does it predict the presence of a proximal culprit lesion along the right coronary artery course?

Objective: Acute inferior myocardial infarction (AIMI) is generally characterized by ST segment elevation in the limb leads (D2, D3, aVF). Many trials have reported the close relation between the severity of this ST segment elevation and the extent of infarction, and also the prognosis. Based on the clinical studies, several electrocardiographic (ECG) criteria have also been propounded to identify the infarct-related artery. This study was conducted to investigate the possible relation between the severity of ST segment elevation and the proximity of the culprit lesion along the right coronary artery (RCA) course in AIMI
