Abstract

Ventricular pacing may interfere with the interpretation of ECG among patients with suspected acute myocardial infarction (AMI), with possible delay of reperfusion therapy. Since left bundle branch block has a similar ECG morphology to right ventricular paced rhythm, Sgarbossa and modified Sgarbossa criteria could be useful in this setting. We present four clinical cases in which a recently proposed clinical-instrumental algorithm has been adopted to manage patients with right ventricular paced rhythm and suspected AMI.

Keywords: Acute coronary syndromes; Acute myocardial infarction; Electrocardiogram; Left bundle branch block; Pacemaker.
