Accelerometer-Based Activity Sensing by an Insertable Cardiac Monitor In Ambulatory Patients: A Subanalysis of LUX-Dx TRENDS (LUX-Dx Heart Failure Sensors in an Insertable Cardiac Monitor System Clinical Study)

Accelerometer-based motion detection is a common feature of cardiovascular implanted electronic devices (CIED) such as pacemakers and defibrillators (ICDs) and has been previously used to monitor patient activity1 and inform rate adaptive pacing2. Continuous activity monitoring may also be useful for ambulatory patients who do not meet the indications for a pacemaker or ICD.
