We report the case of a patient with persistent cardiac rhythm originating from the superior vena cava (3 cm above the vena cava‐atrial junction). It was detected by noncontact balloon mapping before induction of tachycardia and confirmed by conventional contact mapping with image studies. Thus, a 12‐lead ECG showing normal morphologies of P waves may not indicate that the P waves are of sinus node origin.
