Detection of rotational activity in cardiac electrophysiology Universiteit Gent
In one aspect, the invention relates to a device for detecting points and/or regions of rotational electrophysiological activity in or on a heart. The device (1) comprises an input (2) for receiving spatiotemporal electrophysiological data corresponding to a plurality of spatial locations in or on the heart, a time feature extractor (3) for providing, for each spatial location, time values indicative of times of occurrence of a predetermined feature of a plurality of electric potential waveforms at the spatial location, a mapping unit (4) for providing pairs of adjacent spatial locations; a ...
