摘要： An apparatus comprises a transceiver configured to communicate wirelessly with an IMD and a processor communicatively coupled to the transceiver. The processor is configured to detect an error in a data unit received from the IMD, transmit a series of synchronization signals during an uninterrupted communication sequence, and receive, for each synchronization signal, a new data unit and the number of requested duplicate data units from the IMD. Each synchronization signal includes an echo code, wherein the echo code corresponds to a request for a number of duplicate data units to be sent in response to detecting the error in the data unit received during said uninterrupted communication sequence. The number of duplicate data units corresponds to a value of the echo code, and a duplicate data unit corresponds to a data unit previously transmitted by the IMD during said uninterrupted communication sequence.
