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.

1. A method comprising: transmitting, using an external device, a series of synchronization signals during an uninterrupted communication mode, wherein each synchronization signal includes an echo code, wherein the transmitted echo code requests a number of duplicate data units to be sent in response to detecting an error in a data unit received by the external device during said uninterrupted communication mode; andreceiving, using the external device and for each synchronization signal, a new data unit and receiving the number of requested duplicate data units from an implantable medical device (IMD), wherein the number is selected using a value of the echo code, and wherein a duplicate data unit corresponds to a data unit previously transmitted by the IMD during said uninterrupted communication mode. 2. The method of claim 1, wherein transmitting includes transmitting a far field radio frequency signal. 3. The method of claim 1, further including rendering an image on a display using a received new data unit and any received duplicate data units. 4. The method of claim 1, wherein each duplicate data unit corresponds to a previously transmitted new data unit. 5. The method of claim 1, wherein the echo code includes a two bit value. 6. The method of claim 1, wherein the number is selected from the group of 0, 1and 2. 7. The method of claim 1, wherein receiving the new data unit and receiving the number of duplicate data units includes receiving the new data unit before receiving the number of duplicate data units. 8. The method of claim 1, further including generating an error code based on the received new data unit and the number of duplicate data units. 9. The method of claim 8, wherein the echo code is selected as a function of the error code. 10. The method of claim 9, wherein the echo code corresponds to a request for greater than zero duplicate data units. 11. The method of claim 1, wherein the echo code is remotely selectable. 12. The method of claim 1, wherein a data unit may be transmitted multiple times as a duplicate data unit during the same communication sequence. 13. The method of claim 1, wherein at least one unit of real time data from the implantable device is received by the external device for a synchronization signal transmitted by the external device during the uninterrupted communication mode. 14. An apparatus comprising: a transceiver configured to communicate wirelessly with an IMD;a processor communicatively coupled to the transceiver, wherein the processor is configured to:detect an error in a data unit received from the IMD; transmit via the transceiver, during an uninterrupted communication mode, a series of synchronization signals wherein each synchronization signal includes an echo code, wherein the transmitted echo code requests a number of duplicate data units to be sent in response to detecting the error in the data unit received via the transceiver during said uninterrupted communication mode; andreceive via the transceiver, for each synchronization signal, a new data unit and the number of requested duplicate data units from the IMD, wherein the number of duplicate data units corresponds to a value of the echo code, and wherein a duplicate data unit corresponds to a data unit previously transmitted by the IMD during said uninterrupted communication mode. 15. The apparatus of claim 14, wherein the processor is configured to request that a data unit is transmitted multiple times as a duplicate data unit during the same communication sequence. 16. The apparatus of claim 14, including a display communicatively coupled to the processor, and wherein the processor is configured to render an image on the display using a received new data unit and any received duplicate data units. 17. The apparatus of claim 16, wherein the processor is configured to display at least one of electrogram data and marker data using the duplicate data units. 18. The apparatus of claim 17, wherein a data unit includes multiple bytes of at least one of electrogram data and marker data. 19. The apparatus of claim 14, wherein the processor is configured to generate an error code based on the received new data unit and the number of duplicate data units. 20. The apparatus of claim 19, wherein the processor is configured to generate the echo code based on the generated error code. 21. The apparatus of claim 14, wherein the processor is configured to generate the echo code according to a requested data redundancy level entered by a user.
