Abstract:
A data storage system, comprising:history storage nodes each adapted to be allocated to an episode for referencing a location where data related to the episode is stored, the data collected by an implantable medical device; a linked list of unallocated history storage nodes; and a plurality of priority type linked lists of allocated history storage nodes, including: at least one atrial linked list of history storage nodes allocated to atrial tachyarrhythmia response (ATR) episodes; and at least one ventricular linked list of history storage nodes allocated to ventricular tachyarrhythmia response (VTR) episodes, wherein: a history storage node from the linked list of unallocated history storage nodes is allocated to a new episode if the linked list of unallocated history storage nodes is not empty; and a history storage node from one of the priority type linked lists of allocated history storage nodes is selected, based on a predetermined relative priority of each of the priority type linked lists of allocated history storage nodes, for being allocated to the new episode if the linked list of unallocated history storage nodes is empty.
