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!

100 yof CC: Rib pain and intermittent spasms
>>Too perfectly lined up with the T-waves, while the isoelectric line is relatively stable, to be strictly movement artifact. Can these spasms be sync-d with (or caused by) mechanical movement of the heart walls?

What it Looks Like: Cardiac Arrest
Fantastic post, must see stuff for junior paramedics, medical students, residents and nurses that could potentially see cardiac arrest on a regular basis.
