Background: The presence of left bundle-branch block on the electrocardiogram may conceal the changes of acute myocardial infarction, which can delay both its recognition and treatment. We tested electrocardiographic criteria for the diagnosis of acute infarction in the presence of left bundle-branch block. Methods: The base-line electrocardiograms of patients enrolled in the GUSTO-1 Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries trial who had left bundle-branch block and acute myocardial infarction confirmed by enzyme studies were blindly compared with the electrocardiograms of control patients who had chronic coronary artery disease and left bundle-branch block.
The electrocardiographic criteria for the diagnosis of infarction were then tested in an independent sample of patients presenting with acute chest pain and left bundle-branch block. Results: Of 26, North American patients, 0. The three electrocardiographic criteria with independent value in the diagnosis of acute infarction in these patients were an ST-segment elevation of 1 mm or more that was concordant with in the same direction as the QRS complex; ST-segment depression of 1 mm or more in lead V1, V2, or V3; and ST-segment elevation of 5 mm or more that was disconcordant with in the opposite direction from the QRS complex.
We used these three criteria in a multivariate model to develop a scoring system 0 to 10 , which allowed a highly specific diagnosis of acute myocardial infarction to be made. Conclusions: We developed and validated a clinical prediction rule based on a set of electrocardiographic criteria for the diagnosis of acute myocardial infarction in patients with chest pain and left bundle-branch block.

Sgarbossa's criteria are a set of electrocardiographic findings generally used to identify myocardial infarction also called acute myocardial infarction or a "heart attack" in the presence of a left bundle branch block LBBB or a ventricular paced rhythm. The rule was defined by Dr. Elena Sgarbossa, Argentine- born American cardiologist. A scoring system, now commonly called Sgarbossa criteria, was developed from the coefficients assigned by a logistic model for each independent criterion, on a scale of 0 to 5. Three criteria are included in Sgarbossa's criteria: .

Therefore a positive score should be acted upon, but a lower score can not by itself rule out MI - maintain a high index of suspicion if the presentation is consistent with MI. This is an unprecedented time. It is the dedication of healthcare workers that will lead us through this crisis. Thank you for everything you do.
