Modified Sgarbossa Positive ECG Interestingly, the ECG for this case report shows development of conventional STEMI criteria in the patient’s native beats (QRS complex 9, leads V5 and V6). This ECG is unique in that it is negative by the original Sgarbossa criteria of the paced beats but is positive based on the modified Sgarbossa criteria. Namely, QRS complex 10 in lead V6 has ST elevation 2.5mm/S-wave 6mm = 0.42; this is >25% (or 0.25). #Sgarbossa #Positive #ECG #Modified #EKG #Electrocardiogram #Clinical #Cardiology
