Key result
Automatic defibrillator controls VT but precipitates AF as a previously unreported side effect.
Why the study?
The occurrence of atrial fibrillation induced by an implanted automatic defibrillator during ventricular tachycardia reversion was previously unreported.
Case Report (n=1)
This case report highlights a previously unreported side effect of an implanted automatic defibrillator precipitating atrial fibrillation during reversion of ventricular tachycardia.
May warrant vigilance for AF after ICD discharge in VT; single case leaves open reproducibility and clinical impact.
A 54 year old man with refractory life threatening ventricular tachycardia was given an automatic defibrillator. The initial system was a transvenous defibrillator coil electrode and this was later modified by implantation of two patch electrodes at thoracotomy. The modified system successfully controlled ventricular tachycardia. On one occasion reversion of ventricular tachycardia by the defibrillator precipitated atrial fibrillation, a previously unreported side effect.

Jordaens et al. (1985) conducted a case report in Refractory life threatening ventricular tachycardia (n=1). Automatic defibrillator was evaluated on Control of ventricular tachycardia and side effects. An automatic defibrillator successfully controlled ventricular tachycardia but on one occasion precipitated atrial fibrillation, a previously unreported side effect.
