摘要： A system and method for clustering wavefront signals in an electrophysiological map of a cardiac tissue are provided. The system and method include receiving an electrophysiological map of the cardiac tissue, displaying propagation of the wavefront signals as a plurality of velocity vectors, discretizing the received electrophysiological map into a plurality of sections, clustering the velocity vectors into at least one group within each section based on predefined criteria, and generating a trend line representative of each group of clustered velocity vectors within each section in the electrophysiological map.

摘要： In one embodiment, a medical system includes a catheter to be inserted into a chamber of a heart, and including electrodes to capture electrical activity of tissue of the chamber over time, a display, and processing circuitry configured to compute a propagation of a cardiac activation wave over an anatomical map of the chamber from a start time in a cardiac cycle to an end time in the cardiac cycle responsively to the captured electrical activity, render to the display a sub-region of the anatomical map, select a time-bounded portion of the propagation of the cardiac activation wave commencing at a time after the start time responsively to when the propagation would commence to be rendered in the sub-region of the anatomical map, and render to the display the time-bound portion of the propagation of the cardiac activation wave on the sub-region of the anatomical map.

摘要： A method includes inserting a catheter into an organ of a patient and selecting, in a three-dimensional (3D) image of the organ, a plane of interest (POI). A first image, which includes an endoscopic view of the 3D image from a direction facing the POI, is produced. A second image, which includes a sectional view of the 3D image that is clipped by the POI, is produced, and the first and second images are displayed to a user.
