Overview

An anterior myocardial infarction (MI) is a heart attack or cessation of blood flow to the heart muscle that involves the anterior side of the heart. An anterior MI is characterized by the presence of ST elevation in the anterior leads V3 and V4. ST elevation in V1 and V2 corresponds to septal infraction whereas ST elevation in leads V5 and V6 corresponds to apical infarction.

EKG Examples

Shown below is an EKG demonstrating loss of R waves throughout the anterior wall (V1-V6). QS complexes in V3-V5. ST elevation in V1-V5 with terminal negative T waves.

Shown below is an EKG demonstrating a 2 weeks old anterior infarction with Q waves in V2-V4 and persisting ST elevation, a sign of left ventricular aneurysm formation.

Shown below is an EKG demonstrating sinus rhythm. The remarkable feature is the poor R wave progression in the V1 and V2 leads and the ST elevation and T wave changes in leads V1 to V4 and I and aVL. The cardiogram suggests an anterior/ lateral MI possibly acute. There is also terminal P wave negativity in V1 suggesting a left atrial abnormality.
