Abstract

This report presents a verapamil-sensitive atrial tachycardia, mid-atrium septum activating the earliest. Concealed entrainment was obtained at noncoronary aortic sinus (NCS), where the local activation was delayed compared to mid-septum. The tachycardia was successfully ablated at NCS. The entrance of the slow conduction zone was located at NCS.

Keywords: Concealed entrainment; His bundle; noncoronary aortic sinus; slow conduction zone; verapamil‐sensitive atrial reentrant tachycardia.
