Automatic selection method of the evoked response sensing vectors that use the evoked response waveform analysis

摘要

How to select the best evoked response sensing vector based on the evaluation of the quality of the evoked response signal and the cardiac pacing device, is provided. Electrode switching circuit components, to allow for the selection of the detection electrode plurality of vectors. For use when determining the evoked response signal quality parameters, capture detection circuit component provides a loss of capture and signal characteristics acquisition is determined in pacing threshold during the search. Optimal evoked response sensing vector is selected based on the evoked response signal quality parameters to meet for the evoked response detection reliable, the predetermined reference.
