The phenomenon of a 2:1 bundle branch block is reported during atrioventricular (AV) nodal reentrant tachycardia, sinus tachycardia, atrial fibrillation, and atrial flutter. A 2:1 bundle branch block is attributed to first‐ and second‐degree bundle branch block, linking, electrical alternans, aberrancy, or supernormal conduction. However, the same phenomenon has not been reported in AV reentrant tachycardia. Herein, we report the case of a 52‐year‐old man presenting with orthodromic atrioventricular reentrant tachycardia with a 2:1 right bundle branch block.
