eFigure 10–43. An 82-year-old man with past medical history of CAD, COPD, diabetes mellitus type 2, peripheral vascular disease, moderate aortic stenosis, recent nSTEMI (1 month back). His previous coronary angiogram showed proximal LAD and proximal circumflex 90% stenotic lesions. Successful percutaneous coronary intervention with drug-eluting stents was done. He presented to the hospital for evaluation of chest pain that was going on and off for the past 2 days. His initial ECG showed normal sinus rhythm, left axis deviation, and left bundle branch block (LBBB) (A). His troponins × 3 remained flat at 0.06 ng/mL. Subsequent ECG showed LBBB and met Sgarbossa criteria (B). The diagnosis of acute MI was made. (Reproduced with permission from Kumar R, Sinha A. Diagnosis of acute myocardial infarction in left bundle branch block. EC Cardiology, 2018; 5(7):467–472.) A 12 lead electrocardiograph shows the rhythmic tracing indicative of left axis deviation and left bundle branch block. A 12 lead electrocardiograph shows the rhythmic tracing indicative of left bundle branch block and acute M I.
