Rate-adaptive pacing has been a mainstay of bradycardia pacing programming for many yearsThe potential hemodynamic advantages of rate-adaptive modes have been recognized since very early in the rate-adaptive pacing experienceRate-adaptive pacing may be similarly beneficial with cardiac resynchronization therapy (CRT) devicesAn accelerometer incorporated into the tip of the pacing lead, originally known as “peak endocardial acceleration, was originally introduced for bradycardia pacing but is currently used in CRT devices for hemodynamic optimizationEven though some sensors may never have been clinically released as single-sensor rate-adaptive pacing systems, an iteration of the sensor technology could potentially be beneficial for hemodynamic autoregulation in CRT or stand-alone implantable diagnostic devicesThe Sensor and Quality of Life study assessed the effect of single-sensor, minute ventilation, or accelerometer vsdual-sensor programming on quality of life.
