Detailed Description

The study will be conducted in three phases: 1) Screening Phase, 2) Double-blind Randomized phase (1 year), and 3) Unblinded phase (2 years). Patients who are scheduled to undergo implantation of a, or already have an implanted, de novo Astra/Azure pacemaker system, who also have uncontrolled hypertension may be screened for inclusion into this study. All eligible subjects will receive the AVIM RAMware and be randomized 1:1 to either have AVIM therapy turned On or turned Off. All subjects will continue to receive antihypertensive drug therapy.
