Sensing margin detectors for implantable electromedical devices
摘要:
Circuitry for quantitatively determining the level of processed heart signals relative to actual sensing sensitivity level (threshold) in an implantable pacemaker. The measurement is useful for adjusting the settable threshold, polarity, filtering or amplification parameter settings for safe operation and noise rejection of the pacemaker.
