摘要： The present disclosure relates to a medical system (1), comprising a plurality of devices (10, 20, 30) forming nodes of a network, wherein each device (10, 20, 30) of said plurality of devices is configured to communicate with another device in a wireless fashion by receiving a message from another device in the network or by transmitting a message to another device in the network, and wherein a priority is assigned to each device (10, 20, 30), wherein as long as no other transmission of a message is ongoing in the network, each device (10, 20, 30) is configured to initiate a transmission of a message by transmitting a start signal (S1, S2, S3), wherein the higher the priority of the respective device (10, 20, 30), the higher the duration (D1, D2, D3) of the start signal (S1, S2, S3) allocated to the respective device (10, 20, 30), and wherein in case several devices in the network simultaneously initiate a transmission of a message by transmitting a start signal, a permission to transmit a message is automatically granted to the device in the network with the highest priority. Furthermore, the present disclosure relates to a method of communicating in a medical system/network.

摘要： The invention relates to an implantable medical device for stimulating a human or animal heart, comprising a control unit, a memory unit, a stimulation unit for stimulating a cardiac region of a human or animal heart, and a detection unit for detecting an electrical signal of the same heart. The memory unit comprises a computer-readable program that causes the control unit to perform the following steps when executed on the control unit: a) detecting (110), with the detection unit, capture thresholds during an observation period, each capture threshold being detected in response to a sequence of pacing pulses delivered by the stimulation unit; b) storing the detected capture thresholds in the memory unit; c) determining (120) threshold-to-threshold differences between two consecutive capture thresholds in each case; and d) if a maximum determined threshold-to-threshold difference within the observation period is equal to or greater than a predetermined limit, adjusting (140; 170) a pacing output of the stimulation unit on the basis of the maximum capture threshold determined within a first time period, the first time period being equal to or shorter than the observation period; or if the maximum determined threshold-to-threshold difference within the observation period is smaller than the predetermined limit, adjusting (150; 170) the pacing output of the stimulation unit on the basis of the maximum capture threshold determined within a second time period, the second time period being shorter than the first time period.
