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!

Understanding Amiodarone
I like your thought process. A Its not that Amiodarone is contraindicated in Hyperkalemia. In the event of arrest, Hyperkalemia usually leads to PEA and asystole. The Hyperkalemic effects on Action potential and Sodium potassium atpase channels should be addressed first in order for Amiodarone to work effectively. Once this is achieved, proper depolarization and…
