Abstract

Although the most feared cardiac manifestation in cardiac sarcoidosis is the onset of ventricular arrhythmia, some patients may present with supraventricular arrhythmias. We present a rare case of cardiac sarcoidosis associated with double tachycardia manifesting as atrial flutter and ventricular tachycardia.

Keywords: Atrial flutter; Cardiac sarcoidosis; Double tachycardia; Ventricular arrhythmia.

Atrial tachycardia (red arrow) with 3:1 atrioventricular conduction and 18 beats of ventricular tachycardia simultaneously observed on Holter electrocardiography are shown (A). The three-dimensional activation map (inferior view) obtained during ventricular tachycardia (VT) (B). Concealed entrainment observed during VT when pacing was performed at the site of the mid-diastolic potential (DP) (C). The yellow arrows indicate a DP.
