We think this might be relevant to the clinical guidance for Sgarbossa Criteria (MI in LBBB).
Sgarbossa Criteria
Sgarbossa Criteria: Used to identify acute myocardial infarction (AMI) in the presence of Left Bundle Branch Block (LBBB) or ventricular paced rhythm. A score ≥ 3 is highly specific for AMI.
