DEVICE AND METHOD FOR FUSION BEAT DETECTION

摘要

A heart monitoring and/or therapy device for detecting and quantifying fusion beats, wherein the device includes an IEGM signal sensing channel that puts out a recorded IEGM signal and an evaluation unit operatively connected to said IEGM signal sensing channel that detects fusion beats. The evaluation unit comprises or is connected to a template memory including at least a first template electrogram signal and a second template electrogram signal. The evaluation unit compares the recorded IEGM signal with both, the first and the second template electrogram signal and determines at least a first degree of similarity reflecting the similarities between the recorded electrogram signal and the first template electrogram signal, and a second degree of similarity reflecting the similarities between the recorded electrogram signal and the second template electrogram signal. The evaluation unit then calculates a fusion index (FI) from the at least two degrees of similarity.

1. A heart monitoring or therapy device for detecting and quantifying fusion beats comprising
an IEGM signal sensing channel configured to put a recorded IEGM signal showing at least prominent ventricular components; and an evaluation unit operatively connected to said IEGM signal sensing channel and configured to detect fusion beats, wherein said evaluation unit comprises or is connected to at least one template memory comprising at least a first template electrogram signal representing an intrinsic beat and a second template electrogram signal representing a captured beat, and wherein said evaluation unit is further configured to
compare the recorded IEGM signal with both, said first and said second template electrogram signal and todetermine at least two degrees of similarity for the recorded IEGM signal, wherein said at least two degrees of similarity comprise
a first degree of similarity reflecting the similarities between the recorded electrogram signal and the first template electrogram signal, anda second degree of similarity reflecting the similarities between the recorded electrogram signal and the second template electrogram signal; and wherein said evaluation unit is further configured to calculate a fusion index (FI) from said at least two degrees of similarity.
