Barostim is not a defibrillator; rather, it is an innovative neuromodulation device system designed to deliver baroreflex activation therapy for the management of heart failure. While implantable cardioverter-defibrillators (ICDs) monitor heart rhythms and deliver high-energy shocks to terminate dangerous ventricular arrhythmias, the Barostim system works by stimulating the carotid baroreceptors to regulate the autonomic nervous system, reduce sympathetic activity, and improve overall cardiac function and symptoms without delivering defibrillation shocks.
