A Blended Sensor Restores Chronotropic Response More Favorably than an Accelerometer Alone in Pacemaker Patients: The LIFE Study Results

Background: Adaptive rate sensors used in permanent pacemakers incorporate an accelerometer (XL) to increase heart rate with activity. Limited data exists regarding the relative benefit of a blended sensor (BS) (XL and minute ventilation) versus XL alone in restoring chronotropic response (CR) in chronotropically incompetent (CI) patients.
