Baroreceptor stimulation in a patient with preexisting subcutaneous implantable cardioverter defibrillator.

Background: Many patients with severe heart failure (HF) have an indication for baroreflex activation therapy (BAT) and an implantable cardioverter-defibrillator (ICD). Concerns about device-device interactions were addressed in a study with small sample size that concluded combined BAT and ICD therapy is safe. There are no published data, however, concerning device-device interactions between BAT and a subcutaneous ICD (S-ICD).
