Non-physiologic sense detection for implantable medical devices

摘要

Method and apparatus for detection of non-physiologic senses checks the output of the sense amplifier of an implanted medical device where the inputs of the sense amplifier are adapted to connect to a living body for sensing electrical signals representative of physiologic events, and especially heart beats, and if that sense output senses a physiologic event within a predetermined time after a non-physiologic event is sensed by another circuit also connected to receive electrical signals from said living body, then there is reported out a signal indicating that the event sensed by the sense amplifier is of a non- physiologic nature. Various uses are accomplished with the information in these output signals.
