Abstract

Different levels of accelerometer output are monitored separately and the outputs from these separate monitorings are combined with weighted values to produce a more responsive accelerometer output or count signal. The value of the weights varies with the level monitored. The method and apparatus can be used independently or combined with other cardiac demand signals to produce a pacing rate or target pacing rate signal or can provide data for monitoring, research, or therapeutic intervention.
