BEAT ALIGNMENT AND SELECTION FOR CARDIAC MAPPING

摘要

This invention relates to the determination and/or representation of physiological information relating to a heart surface.

主权项

1. A method comprising:
for each of multiple, different catheter positions in a heart cavity, concurrently measuring signals at one or more electrodes on a catheter in response to electrical activity in the heart cavity and collecting a plurality of additional data signals; computing criteria for the plurality of additional data signals based on a comparison of the plurality of additional data signals and a template set; selecting a subset of less than all of the signals measured by the one or more electrodes by determining whether to include the signals for a cardiac beat in the subset of less than all of the signals from the comparison of the plurality of additional data signals and the template set; and determining physiological information at multiple locations of the endocardium surface based on the subset of less than all of the signals measured by the one or more electrodes at the different catheter positions by processing the subset of less than all of the signals measured by the one or more electrodes.
