  • Patent number: 11160481
    Abstract: A method including calculating, at multiple intra-cardiac locations, respective average atrial fibrillation cycle-length (AFCL) values. A determination is made as to whether the calculated average AFCL values are indicative of a regular atrial fibrillation (AF) activity. Gradients between pairs of the average AFCL values are calculated for a plurality of average AFCL values that are determined to be indicative of regular AF activity. The calculated AFCL gradients are presented to a user, overlaid on a map of at least a portion of the heart.

  • Publication number: 20210307862
    Abstract: Methods, apparatus, and systems are provided for facilitating the navigation of a catheter between first and second locations within a subject based on display of serial images corresponding to positions of the catheter at successive incremental times. Image production includes sensing catheter positions to produce location data for each time increment. For each position Pi, the corresponding location data is processed to respectively produce an image Ii reflecting the position of the catheter at a time Ti. Each image Ii is successively displayed at a time equal to Ti+d, where d is an image processing visualization delay. Upon a condition that the catheter is displaced to a selected interim location between the first and second locations, the processing of the location data is switched from being performed by a first process associated with a first visualization delay to a second process associated with a second different visualization delay.

  • Patent number: 10898093
    Abstract: Apparatus for assessing scarring of cardiac tissue, consisting of a probe and a processor. The probe has one or more electrodes, which are configured to contact the tissue at a plurality of positions and to sense respective voltages in the tissue at the positions. The processor receives the respective voltages, and computes a triangular mesh that is representative of a surface of the tissue and that consists of multiple triangles having vertices corresponding to the positions contacted by the one or more electrodes. The processor calculates respective scar areas within the triangles by comparing the respective voltages sensed at the positions corresponding to the vertices to a predefined range of the voltages that is associated with scarring, and computes a sum of the respective areas. The processor compares the sum to a total area of the triangles so as to assess a degree of the scarring of the tissue.

  • Publication number: 20200163582
    Abstract: A probe generates location signals, and has an electrode at a distal end which acquires from heart chamber surface positions electrical signals due to a conduction wave traversing the surface. A processor derives LATs from the electrical signals, calculates a first time difference between LATs at a first pair of positions and a second time difference between LATs at a second pair of positions. The processor calculates first and second LAT-derived distances as products of the first and second time differences with a conduction wave velocity, identifies an arrhythmia origin at a surface location where a first difference in distances from the location to the first pair of the positions is equal to the first LAT-derived distance, and a second difference in distances from the location to the second pair of the positions is equal to the second LAT-derived distance, and marks the origin on a surface representation.
