TECHNIQUES FOR DATA RETENTION UPON DETECTION OF AN EVENT IN AN IMPLANTABLE MEDICAL DEVICE

摘要

Methods and apparatus for storing data records associated with a medical monitoring event in a data structure. These include initiating loop recording in an implantable medical device upon determination of a neurological event, wherein loop recording comprises storing a data record of a plurality of data records in a data structure, the plurality of data records representing information about determined neurological events. Methods and apparatus can further include determining a priority index for the plurality of data records based on severity levels of the determined neurological events and replacing older data records of the plurality of data records on the data structure with new data records according to the priority index, wherein the new data records selectively replace those data records in the data structure having the lowest associated priority index.

1. A method of selective data retention in an implantable medical device, the method comprising:
sensing a neurological event; creating a data record of the neurological event; determining a severity level of the neurological event; storing the data record in a data structure containing a plurality of data records, the plurality of data records representing information about a plurality of neurological events; determining a priority index for the plurality of data records based on severity levels of the determined neurological events; and selectively replacing an existing data record in the data structure with a newer data record that has a higher priority index than the existing data record.
