A medical system comprising an active implantable medical device (IMD, 10) and an extracorporeal device attached to a patient's skin, wherein the IMD comprises - a measurement unit adapted to determining data regarding at least one bodily parameter of the patient when the IMD is implanted within a body of the patient, - a processor adapted to process data regarding the at least one bodily parameter and to detect at least one condition associated with a plurality of predefined conditions based on the data, - a communication unit adapted to periodically send an intra-body communication signal representing the at least one detected condition to the extracorporeal device, wherein the extracorporeal device comprises - a transceiver unit adapted to receive the intra-body communication signal, - a notification unit adapted to provide at least one predefined notification signal to the patient to motivate the patient to perform a predefined action based on the received intra-body communication signal, wherein the transceiver unit of the extracorporeal device is further adapted to send a termination signal to the communication unit of the IMD, and wherein the communication unit of the IMD is further adapted to receive the termination signal and to subsequently terminate sending the intra-body communication signal which was initiated by the previously at least one detected condition, wherein the transceiver unit of the extracorporeal device is configured to send the termination signal to the communication unit of the IMD when the notification signal is acknowledged by the patient. wherein the IMD comprises - a measurement unit adapted to determining data regarding at least one bodily parameter of the patient when the IMD is implanted within a body of the patient, - a processor adapted to process data regarding the at least one bodily parameter and to detect at least one condition associated with a plurality of predefined conditions based on the data, - a communication unit adapted to periodically send an intra-body communication signal representing the at least one detected condition to the extracorporeal device, wherein the extracorporeal device comprises - a transceiver unit adapted to receive the intra-body communication signal, - a notification unit adapted to provide at least one predefined notification signal to the patient to motivate the patient to perform a predefined action based on the received intra-body communication signal, - a measurement unit adapted to determining data regarding at least one bodily parameter of the patient when the IMD is implanted within a body of the patient, - a processor adapted to process data regarding the at least one bodily parameter and to detect at least one condition associated with a plurality of predefined conditions based on the data, - a communication unit adapted to periodically send an intra-body communication signal representing the at least one detected condition to the extracorporeal device, wherein the extracorporeal device comprises - a transceiver unit adapted to receive the intra-body communication signal, - a notification unit adapted to provide at least one predefined notification signal to the patient to motivate the patient to perform a predefined action based on the received intra-body communication signal, wherein the transceiver unit of the extracorporeal device is further adapted to send a termination signal to the communication unit of the IMD, and wherein the communication unit of the IMD is further adapted to receive the termination signal and to subsequently terminate sending the intra-body communication signal which was initiated by the previously at least one detected condition, wherein the transceiver unit of the extracorporeal device is configured to send the termination signal to the communication unit of the IMD when the notification signal is acknowledged by the patient.
