Ventricular tachycardia and cardiac sarcoidosis: correspondence between MRI and electrophysiology

Abstract

A 44-year-old woman with a history of histologically proved pulmonary and mediastinal sarcoidosis and chronic atrial fibrillation presented with palpitations followed by syncope. Clinical examination was normal except for arrhythmia and discrete swelling of the ankles. ECG showed the onset of ventricular tachycardia (VT) [ventricular rate 210 b.p.m. and left bundle branch block (BBB) contour and horizontal axis] with sudden hypotension and lipothymia leading to external defibrillation. Subsequent ECG tracings showed sinus rhythm (50 b.p.m.) and complete right BBB. Biology …
