Abstract:
1. A communication unit for conducting wireless communication with an implantable medical device, said communication unit comprises: a receiver connected to a radio frequency antenna and configured to receive data packets transmitted by said implantable medical device; a power down request processor configured to generate a power down request defining a power down of at least one of a transmitter and a receiver of said implantable medical device; a transmitter connected to a radio frequency antenna and configured to wirelessly transmit said power down request to said implantable medical device; a size processor configured to determine the size of data packets received by said receiver and originating from said implantable medical device or transmitted by said transmitter to said implantable medical device; a timer processor connected to said size processor and configured to set a timer to a value defined based on the size of a data packet determined by said size processor; and a processor controller connected to said power down request processor and configured to selectively control said power down request processor to generate or stop generating said power down request based on a current value of said timer; wherein said timer processor is configured to reduce said current value of said timer with a predefined reduction value each time said receiver receives an intracardiac electrogram, IEGM, message from said implantable medical device.
