Patients implanted with a new Guidant ICD/ CRT-D: Indication for CRT-D and ICD with history of atrial fibrillation. Patients with new implants will not be enrolled until their three month follow up visit in the pacemaker clinic.
Patients currenlty implanted with a Guidant ICD/ CRT-D: More than 20% atrial fibrillation burden as recorded by defibrillator follow up report or with history of atrial fibrillation.
Be between 18-85 years old
Be willing and able to give informed consent
Patient currently has a CRT-D or ICD with > 20% atrial fibrillation burden as recorded by defibrillator follow up report or a history of atrial fibrillation prior to implant.
Patient has the ability to complete a Six minute walk test with the only limiting factors to be fatigue or shortness of breath.
Expected mortality less than 6 months due to non-cardiac causes.
