Abstract

We present a case of supraventricular tachycardia (SVT) with discordant RP intervals on 12‑lead ECG, rendering the diagnosis initially challenging. However, clues present on the ECG during SVT along with an ECG in sinus rhythm helped to elucidate the mechanism and the underlying diagnosis.

Keywords: AVRNT; Bayés syndrome; Interatrial block; Supraventricular tachycardia.
