Outcome Measures

Primary Outcomes (1)

  • Peak Volume of Oxygen Uptake (Peak VO2) - Rate Adaptive Pacing (RAP) On at One Month vs. Rate Adaptive Pacing (RAP) Off at One Month.

    Randomized therapy order cross-over comparison at 1 month post-implant. Each patient evaluated for endpoint with and without RAP therapy at this time.

    1 month post implant

Secondary Outcomes (1)

  • Peak Volume of Oxygen Uptake (Peak VO2) - Rate Adaptive Pacing (RAP) On at Six Months vs. Rate Adaptive Pacing (RAP) Off at One Month.

    6 months post implant

Study Arms (2)

RAP On then Off at 1 month visit

EXPERIMENTAL

1. Rate Adaptive Pacing (RAP) On for first cardiopulmonary exercise test (CPX) at one month. 2. Rate Adaptive Pacing (RAP) Off for second cardiopulmonary exercise test (CPX) at one month.

Device: Insignia Plus / Ultra (Guidant/Boston Scientific)

RAP Off then On at 1 month visit

EXPERIMENTAL

1. Rate Adaptive Pacing (RAP) Off for first cardiopulmonary exercise test (CPX) at one month. 2. Rate Adaptive Pacing (RAP) On for second cardiopulmonary exercise test (CPX) at one month.

Device: Insignia Plus / Ultra (Guidant/Boston Scientific)

Interventions

Cardiac pacing using any Guidant/Boston Scientific Implantable Pacemaker System with rate-modulation and any compatible intracardiac lead system.

Also known as: Guidant or Boston Scientific implantable pacemakers

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients who are in sinus rhythm
  • Patients who are on stable medical therapy
  • Patients who exhibit signs and symptoms of heart failure, New York Heart Association (NYHA) Class II or III
  • Patients who have experienced a hospitalization for decompensated heart failure; treatment for pulmonary congestion or volume overload; chronic treatment with a loop diuretic; or a brain natriuretic peptide (BNP) \> 125 ng/l.
  • Left ventricular ejection fraction (LVEF) ≥ 50%

You may not qualify if:

  • Patients with persistent atrial fibrillation or atrial flutter
  • Patients who are in complete heart block
  • Patients who have experienced a recent myocardial infarction (MI) or have unstable angina or require cardiac surgery or other procedures
  • Patients who have severe heart valve disease or valve replacement
  • Patients with a contraindication for a pacemaker system
  • Patients who have a neuromuscular, orthopedic or other non-cardiac condition that prevents patient from exercise testing
  • Patients who have infiltrative or hypertrophic cardiomyopathy
  • Patients who have known severe pulmonary disease
  • Patients with uncontrolled diabetes or blood pressure (systolic blood pressure (SBP) \> 160 mmHg or diastolic blood pressure (DBP) \> 95 mmHg)
