摘要： A communication system for wireless data transmission between an implantable medical device (IMD) and an external device and a respective communication method are disclosed aiming at the increase of longevity of an IMD energy source. The communication system comprises a communication unit and a processor. The IMD is configured to monitor a bodily parameter of a patient and/or is configured to deliver a therapy signal to the patient, wherein the IMD comprises a transceiver module configured to exchange the data with the communication unit of the external device in an uplink direction from the transceiver module to the communication unit and in a downlink direction from the communication unit to the transceiver module. Further, a respective computer program product and computer readable data carrier is described.

摘要： A medical device for determining an extremum of a periodic physiologic signal, comprising a computing unit, a memory unit, and a detecting unit configured to detect a periodic physiologic signal of a human or animal. In operation, the device performs the following steps: detecting a periodic physiologic signal with the detecting unit; dividing the periodic physiologic signal into a plurality of equally long intervals having an interval length, wherein the interval length is chosen such that it is longer than an expected maximum periodic time of the periodic physiologic signal; determining an absolute maximum and/or an absolute minimum of the periodic physiologic signal within each interval; calculating an average value of the determined absolute maxima and/or an average value of the determined absolute minima; storing or outputting the calculated average values of the determined absolute maxima and/or the determined absolute minima as extremum of the periodic physiologic signal.
