Acute anterior wall myocardial infarction entailing st‐segment elevation in lead v1: Electrocardiographic and angiographic correlations

Background: The correlation between ST elevation in lead V1 during anterior wall acute myocardial infaction (AMI) and the culprit lesion site in the left anterior descending (LAD) coronary artery is poor. Hypothesis: The study was undertaken to assess the electrocardiographic (ECG) characteristics a...

Description
Summary:Background: The correlation between ST elevation in lead V1 during anterior wall acute myocardial infaction (AMI) and the culprit lesion site in the left anterior descending (LAD) coronary artery is poor. Hypothesis: The study was undertaken to assess the electrocardiographic (ECG) characteristics and angiographic significance of ST‐segment elevation in lead V1 during anterior wall acute myocardial infarction (AMI). Methods: Data from 115 patients with anterior wall AMI, who underwent coronary angiography within 14 days of hospitalization, were studied. The admission 12‐lead ECG was examined and the coronary angiogram was evaluated for the nature of the conal branch of the right coronary artery (RCA) and for the culprit lesion site in the left anterior descending (LAD) coronary artery. Results: Mean ST‐segment deviation and the frequency of patients with ST‐segment elevation > 0.1 mV were significantly lower in lead V i than in lead V2 (0.136 $$ 0.111 mV vs. 0.421 $$ 0.260 mV, and 37 vs. 96%, for leads Vi and Vi, respectively). A small conal branch not reaching the interventricular septum (IVS) was more prevalent among patients with ST‐segnicni elevation >0.1 mV in lead Vi (67%), whereas a large conal branch was more prevalent in patients with ST‐segment deviation (1 mV in that lead (83%, p
