Zones of MI, leads and ECG mnemonic

Hey!

Warning: This is an over simplified post. 

If you are the kind who has a tough time remembering changes in "which lead" correlates with the "where" the heart is injured, this post is for you xD

Elevation of ST segment indicates zone of injury, diagnosis is supported by reciprocal changes, ST segment depression in the leads facing the opposite wall.

For precordial leads, I use the "SAL" mnemonic.

V1 Septal

V2 Septal

V3 Anterior

V4 Anterior

V5 Lateral

V6 Lateral

To be more complete about the lateral wall involvement, I use the "SALLI" mnemonic.

L for aVL and I for lead I.

So for lateral wall MI: V5 , V6, aVL and lead I.

For inferior MI, I remember the word "INF" and the vertical lines in them:

II vertical lines in the letter "N"
III vertical lines in the word "IN"
The F in "inF" is for avF

So for inferior wall MI: II , III and aVF.

Inferior wall MI mnemonic

By the end of this post, you should be able to draw this cheat sheet yourself:

That's all!
