Patent ID: 8768443

Claim:
An external patient management system for determining atrial arrhythmia burden, comprising: an external database configured to centrally maintain sets of parametric data obtained from an implantable medical device through interrogation; the external patient management system configured to execute an analysis module to calculate an atrial arrhythmia burden, the analysis module comprising: an episode submodule configured to identify a cumulative atrial tachyarrhythmia duration for each atrial tachyarrhythmia episode recorded in the parametric data over a look back period, wherein the duration of the look back period is measured from the time of the end of each atrial tachyarrhythmia episode if the atrial tachyarrhythmia episode has concluded before interrogation of the implanted device or from the time of interrogation of the implanted device if the most recent atrial tachyarrhythmia episode is still in progress at the time of interrogation; and a counter submodule configured to evaluate therapy duration counter data obtained from the implantable medical device.
