IDENTIFICATION OF HEALTHY VERSUS UNHEALTHY SUBSTRATE FOR PACING FROM A MULTIPOLAR LEAD

摘要

A medical device system performs a method determining presence of scar tissue. Torso-surface potential signals are received by a processor from multiple electrodes distributed on a torso of a patient. The processor extracts features of the potential signal from each electrode and stores values of the features in a non-transitory storage medium. The processor determines a scar indicator index for each of the electrodes from the stored features and identifies which ones of the electrodes have an affirmative scar indicator index. An overall scar burden index is determined as a proportion of the electrodes with an affirmative scar indicator index.

主权项

1. A system for determining presence of myocardial scar tissue, comprising:
a processor receiving means for receiving a torso-surface potential signal from each of a plurality of electrodes distributed on a torso of a patient; a processor means for extracting features of the potential signal from each of the plurality of electrodes; a storing means for storing the features; a processor means for determining a scar indicator index for each of the plurality of electrodes from the stored features, identifying ones of the plurality of electrodes having an affirmative scar indicator index, and determining an overall scar burden index as a proportion of the plurality of electrodes with an affirmative scar indicator index.
