The “rSr′ ECG pattern” is not always a Brugada ECG pattern

Abstract

The differential diagnosis of an rSr′ pattern in leads V1 and V2 on the surface electrocardiogram (ECG) is a common issue in daily practice. This ECG pattern can be found in patients with prior cardiovascular disease, or in completely asymptomatic individuals as part of their routine medical exam. 1 The differential diagnoses should include Brugada syndrome, arrhythmogenic right ventricular dysplasia (ARVD), complete and incomplete right bundle branch block (RBBB), and normal variants in healthy individuals and athletes. 2
