Direct current cardioversion for atrial fibrillation induced a sudden dramatic heart rate change associated with multiple ventricular fibrillation arrests in a reported case.
Direct current cardioversion for atrial fibrillation can rarely be associated with sudden heart rate changes leading to ventricular fibrillation arrests.

Alerts clinicians to rare VF risk during AF cardioversion; single case leaves incidence and mechanisms open.
Cardioversion remains an important therapy in the management of atrial fibrillation. Here, we report a case where direct current cardioversion resulted in a sudden dramatic change of heart rate that was associated with multiple ventricular fibrillation arrests in a manner akin to that previously observed post-atrioventricular node ablation.
