Abstract
Methods, systems, and computer program products differentiate between arrhythmic events having different origins. An implantable medical device detects the arrhythmic events. At least one method involves receiving electrograms representing arrhythmic events and sorting the arrhythmic events into groups based on similarities between the electrograms and/or differences between the electrograms. The method also involves identifying an exemplary arrhythmic event from each group to represent the group from which the exemplary arrhythmic event is identified and distinguishing each exemplary arrhythmic event via an interface display.
Claims20
A method for differentiating arrhythmic episodes having different origins, wherein the arrhythmic episodes are detected in a patient by an implantable medical device, the method comprising:
- receiving electrograms that represent the arrhythmic episodes detected by the implantable medical device;
- sorting the arrhythmic episodes into groups based on at least one of similarities between the electrograms or differences between the electrograms;
- identifying an exemplary arrhythmic episode from each group of the groups of the sorted arrhythmic episodes to represent the each group;
- and
- distinguishing the exemplary arrhythmic episode of the each group by highlighting the exemplary arrhythmic episode among other arrhythmic episodes of the each group via an interface display.
A computer program product comprising a computer-readable medium having control logic stored therein for causing a computing apparatus to differentiate between arrhythmic episodes detected in a patient, the control logic comprising computer-readable program code for causing the computing apparatus to:
- receive electrograms representing arrhythmic episodes;
- sort the arrhythmic episodes into groups based on similarities between the electrograms;
- identify an exemplary arrhythmic episode from each group of the groups of the sorted arrhythmia episodes to represent the each group;
- and
- distinguish the identified exemplary arrhythmic episodes by highlighting the identified exemplary arrhythmic episodes among other arrhythmic episodes via an interface display.
A computer-implemented system for differentiating between arrhythmic episodes having different origins, wherein the arrhythmic episodes are detected in a patient by an implantable medical device, the system comprising:
- an external programmer including an interface display, the external programmer operative to:
- receive electrograms that represent arrhythmic episodes detected by the implantable medical device;
- sort the arrhythmic episodes into groups based on at least one of similarities between the electrograms or differences between the electrograms;
- identify an exemplary arrhythmic episode from each group of the groups of the sorted arrhythmic episodes to represent the each group;
- and
- distinguish each exemplary arrhythmic episode of the identified exemplary arrhythmic episodes via the interface display by highlighting the each exemplary arrhythmic episode among other arrhythmic episodes.
