In the Cardiac Sarcoidosis Consortium, arrhythmias were common in patients with cardiac sarcoidosis, with NSVT occurring in one third of patients (A). On 24‐hour Holter monitoring in 164 patients with cardiac sarcoidosis, NSVT occurred more frequently in patients with left ventricular ejection fraction <50% (B), and PVCs occurred more commonly in male patients (C). Arrhythmia outcomes in 587 patients with cardiac sarcoidosis enrolled in the Cardiac Sarcoidosis Consortium, divided into 2 groups according to the presence or absence of adverse events, defined as death, left ventricular assistance device implantation, heart transplantation, and appropriate implantable cardioverter‐defibrillator shock or pacing (D). AFib indicates atrial fibrillation; AFlutter, atrial flutter; AVB, atrioventricular block; EF, ejection fraction; NSVT, nonsustained ventricular tachycardia; PVC, premature ventricular contraction; and VT, ventricular tachycardia.
