Summary

The goal of this trial is to test the effect/benefit of a FDA approved blended pacemaker sensor which responds only by comparing physical activity, heart rate, and breathing rate; compared to the accelerometer pacemaker sensor which respond only by comparing physical activity and the heart rate in patients whose heart is unable increase its heart rate according to increase physical activity or demand (Chronotropic Incompetence). Only one pacemaker family will be used in this clinical trial whereas the "out of box" configuration is the blended sensor which can also be made to act only as an accelerometer.

Conditions

  • Chronotropic Incompetence

Interventions

DEVICE

Blended Sensor Optimization (BSO)

At wound check (POD#1 and 1 Week F/U), histograms from device interrogation obtained from patients in the BSO group are assessed, and these patients undergo optimization. A hall walk and stair climbing exercise will be performed and MV optimized using trending data to hit the following targets: HR at Rest: 60 HR upon slow walking: 100 HR upon brisk walking: 115-120 HR upon climbing stairs: 130-135 Patients will undergo optimization, and be instructed that their device may have been optimized.

DEVICE

Accelerometer Alone (AA)

Patients in the AA group will also undergo device interrogation, and will perform a hall walk and stair climbing exercise. Afterwards, these patients will undergo a sham optimization by placing the PPM interrogation laptop device over there pacemaker, and instructing the patients that their device may have been optimized.
