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 option was indeed turned on! As for non-CP presentations of ACS, I absolutely believe that these warrant the same level of urgency as the "typical" presentations. Both men and women, young and old, all commonly present without classic chest pain. Besides, how much difference is there between "burning in the epigastrium," and "pain in…

You took the words right off of my keyboard, Jason! A little bit of critical thinking works wonders when faced with "protocol versus best interests of the patient" type decisions. Not to encourage deviation from protocols and such, but it is a much less severe trespass if you bend the rules a bit as long…

My uninformed opinion? I pretty much agree with AHA - if they aren't hypoxic, no need. I'm not sure how terrible superoxia really is, short-term, but why bother if it doesn't help?

Chris Watford- as you probably know the "acute MI suspected" detection function in the LP12/15 is a programable option. I suspect the software didn't miss this but rather it wasn't turned on. As for treatment everyone has pretty much got it down. Finally as for activation. Absolutely! Don't real care if the protocol allows for…

There's not much I think I can add at this point, but I will comment on a couple of things. The reciprocal changes indicate to me that there is likely RCA involvement. Also, I've recently been hearing quite a bit about withholding O2 in ACS patients like this. Dr. Walsh, do you have any opinions…
