Abstract
The system of the present invention records and stores, in long-term memory and in form of data snapshots, medical data acquired prior to and subsequent to an occurrence of cardiac episodes and implantable device functions defined as important by the medical practitioner. The system provides the medical practitioner with the ability to specify trigger criteria representative of important cardiac episodes and implantable device functions. The system of the present invention allows the medical practitioner to control the amount of medical data stored in the data snapshots. The system allows the medical practitioner to specify a mode of storing data snapshots when the maximum storage capacity of long-term memory has been reached. In a first mode, the system stores data snapshots in a circular buffer manner, overwriting the older data snapshots. In a second mode, the system stops storing new data snapshots after the maximum storage capacity of long-term memory has been reached.
