Atrial tachycardia or ”atypical” atrial flutter? Clinician’s dilemmas resolved by electrophysiologist

Abstract

We present a case report of a patient who underwent ablation of “atypical” atrial flutter. In the surface electrocardiogram, atrial tachycardia was initially diagnosed. As a result of electrophysiological mapping using the CARTOPRIME module, the diagnosis was verified and “atypical” atrial flutter was diagnosed, whose propagation wave in the right atrium met the criteria for the diagnosis of typical atrial flutter.
