Anterior MI

This is part of: Myocardial Infarction

ECG-characteristics:[1]

Anterolateral infarct caused by occlusion of the LAD.

ST-elevation in leads V1-V6, I and aVL. Maximum elevation in V3, maximal depression in III
later: pathological Q-wave in the precordial leads V2 to V4-V5.

Encomprises the anterior part of the heart and a part of the ventricular septum. Is supplied by blood by the LAD.

Examples

• 

  A typical example of an acute anterior wall infarction. ST elevation in leads I, AVL and V2-V5. Reciprocal depressions in the inferior leads (II,III,AVF)

• 

  A 2 weeks old anterior infarction with Q waves in V2-V4 and persisting ST elevation, a sign of formation of a cardiac aneurysm.
