Sgarbossa's Criteria – New Graphic

Here is a graphic I created to help explain Sgarbossa’s criteria for identifying acute myocardial infarction (AMI) in the presence of left bundle branch block (LBBB) or paced rhythm.

In a previous article I showed this graphic which was created using PowerPoint.

Here is a similar graphic I created this morning by cropping actual ECGs that meet the criteria.


These are the features we should be looking for with LBBB and ventricular paced rhythms!

The role of 12 lead ECG in Pediatric Pulmonary Hypertension
Precision of discussion is noteworthy. It helped a lot to understand PAH in an ECG. Thanx much Ivan Rios.

Thanks for writing Tyler. They are the same thing. Strain pattern is just the result of increased pressures against the ventricles which alters the way repolarization occurs from epicardium to endocardium. Similar to stepping on a puddle of water. Your show spreads the water away from the area of pressure. The ST segment is slightly…

Can you explain how these ST segment and T wave changes can be differentiated from right strain pattern?
