Sgarbossa Criteria Calculator
For ECG assessment of suspected acute myocardial infarction in patients with left bundle branch block (LBBB). This calculator uses the classic Sgarbossa point-based criteria.
Clinical safety note: This tool is for educational and clinical
decision-support use only. It does not diagnose MI by itself. Use with symptoms,
serial ECGs, troponins, haemodynamic status, and urgent cardiology/emergency
assessment when appropriate.
