    摘要： A method for storing digitized electrogram and diagnostic data in a read/write memory of an implantable cardiac therapy device which includes the steps of configuring the memory into first and second memory blocks, configuring the first memory block into a plurality of successive EGM data records for storage of the electrogram data, and the second memory block into a plurality of successive diagnostic data records for storage of the diagnostic data, storing successive electrogram data corresponding to successive EGM trigger events in respective, successive ones of the EGM data records, and, storing successive diagnostic data corresponding to successive diagnostic trigger events in respective, successive ones of the diagnostic data records. The electrogram data is preferably written into the EGM data records in a wraparound, FIFO manner. The memory preferably includes an EGM directory having a plurality of cross-indexed entries each containing several fields of relational data concerning associated ones of the electrogram data records, and a diagnostic directory having a plurality of cross-indexed entries each containing several fields of relational data concerning associated ones of the diagnostic data records, to thereby provide a relational database of electrogram and diagnostic data for subsequent telemetric interrogation by an external instrument.
