This is an awesome PowerPoint presentation from one of my favorite ECG textbooks, 12-Lead ECG - The Art of Interpretation.

You owe it to yourself to purchase this book (and no, they don't pay me to say that).

Make sure you use "full screen" so you can see all of the features of this important presentation. Pay special attention to slides 33-47!

Slide 45 shows a strain pattern from left ventricular hypertrophy (LVH).

Slide 47 shows a split screen with a strain pattern from right ventricular hypertrophy (RVH) on the left and acute infero-posterior STEMI on the right.

This is the book that taught me how to recognize strain patterns! So pay attention because this is one of the most important STEMI mimics!
