Use of a wireless implantable cardioverter defibrillator in a patient with a preexisting neurostimulator.

We report the case of a 54-year-old man with a previously implanted neurostimulator who presented with palpitations and was found to have sustained ventricular tachycardia on electrophysiologic study. A Medtronic wireless implantable cardioverter defibrillator (ICD; Medtronic Inc., Minneapolis, MN, USA) with home monitoring (HM) was successfully implanted. Interaction testing during implantation, follow-up, and HM showed that there was no device-device interaction.
