ABSTRACT:
There is provided a pacemaker having automatic adjustment of the sensitivity for sensing cardiac signals such as QRS, T and P waves. The pacemaker has software for examining each inputted signal, obtaining a measure of the peak amplitude, e.g. one-half, comparing such measure with a stored software sensitivity level, and adjusting the software sensitivity level each beat so that it effectively tracks beat-to-beat changes in the signal amplitude. The adjusted software sensitivity level is used for determining when an input signal is to be accepted as a true signal, or rejected.
