Abstract
The present disclosure is directed to generating and displaying an electrogram (EGM) summary for use by physicians or other clinicians. An implantable medical device (IMD) transmits EGM signal data for a number of cardiac episodes to an external computing device. The external computing device selects a subset of the cardiac episodes for which information or images are displayed to the user. In various examples, cardiac episodes may be selected for display based at least in part on a retrospective analysis classification of the cardiac episode.
Claims24
A method comprising:
- receiving cardiac electrogram (EGM) signal data from an implantable medical device (IMD), the EGM signal data including a plurality of detected cardiac episodes, each of the plurality of cardiac episodes classified by the IMD as at least one of a ventricular tachycardia/ventricular fibrillation (VT/VF) episode, a supraventricular tachycardia (SVT) episode, a ventricular tachycardia non-sustained (VTNS) episode, an atrial tachycardia/atrial fibrillation (AT/AF) episode, a monitored VT episode, or a ventricular oversensing (VOS) episode;
- conducting a retrospective analysis of each of the plurality of cardiac episodes, the retrospective analysis providing a retrospective analysis classification;
- and
- selecting, using a processor, a subset of the plurality of cardiac episodes for display based at least in part on at least one of the IMD classification and the retrospective analysis classification, wherein for each episode category including at least one episode, the subset includes greater than or equal to one episode and less than or equal to a predetermined number of episodes.

A system comprising:
- a communication module configured to receive electrogram (EGM) signal data from an implantable medical device, the EGM signal data including a plurality of cardiac episodes, each of the plurality of each of the plurality of cardiac episodes classified by the implantable medical device as at least one of a ventricular tachycardia/ventricular fibrillation (VT/VF) episode, a supraventricular tachycardia (SVT) episode, a ventricular tachycardia no stimulation (VTNS) episode, an atrial tachycardia/atrial fibrillation (AT/AF) episode, a monitored VT episode, or a ventricular oversensing (VOS) episode;
- a processor configured to:
- conduct a retrospective analysis for each of the plurality of cardiac episodes, the retrospective analysis providing a retrospective analysis classification;
- and
- select a subset of the plurality of cardiac episodes for display based at least in part on at least one of the implantable medical device classification and the retrospective analysis classification, wherein for each episode category including at least one episode, the subset includes greater than or equal to one episode and less than or equal to a predetermined number of episodes;
- and
- a graphical user interface configured to display a summary of the selected subset of the plurality of cardiac episodes.
