The Effect of Blended Sensor Efficiency on Relieving the Heart's Inability to Increase Its Rate During Exercise

"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."

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.
