Abstract

Ventricular fibrillation (VF) is a lethal arrhythmia that requires immediate cardioversion and is rarely self-terminating. Spontaneous termination is typically associated with more organized activation than sustained VF terminated by shock, but the precise mechanism is unclear. In the present case, we describe a patient with recurrent syncope and documented self-terminating VF, who ultimately underwent implantable cardioverter defibrillator insertion. Assessment of the rhythm strip revealed organization of a chaotic rhythm into monomorphic ventricular tachycardia before termination, in supportive of previous reports. In conclusion, self-terminating VF is a very rare condition that can cause syncope.
