Patent number: 11857307Abstract: A probe generates location signals, and has an electrode at a distal end that 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.Type: GrantFiled: August 8, 2022Date of Patent: January 2, 2024Assignees: BIOSENSE WEBSTER (ISRAEL) LTD., RUTGERS, THE STATE UNIVERSITY OF NEW JERSEYInventors: Gal Hayam, Michael Timofeyev, Tal Haim Bar-On, Amardeep Saluja

Publication number: 20230172519Abstract: A method includes receiving a bipolar signal sensed by a pair of electrodes at a location in a heart of a patient. One or more electrocardiogram (ECG) signals are received, sensed by body-surface electrodes attached to the patient. Two or more successive QRS complexes are identified in the bipolar signal. One or more activations are detected in the bipolar signal, which occur within a window-of-interest that begins at least a given time with respect to the identified QRS complexes. The detected activations are checked whether they are late potentials, by verifying whether (i) the activations do not coincide with a predefined event observed in the ECG signals, and (ii) the activations are repeatable in the successive QRS complexes. In response to deciding that at least one of the detected activations is a late potential, the latest of the at least one of the late potentials is visualized to a user.Type: ApplicationFiled: February 2, 2023Publication date: June 8, 2023Inventors: Refael Itah, Natan Sharon Katz, Yaron Kadoshi, Gal Hayam, Elad Nakar, Tal Haim Bar-on, Eliyahu Ravuna, Lior Botzer, Yoav Benaroya, Nuno Miguel Rocha Coretez-Diaz

Patent number: 11523875Abstract: 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.Type: GrantFiled: April 6, 2020Date of Patent: December 13, 2022Assignee: Biosense Webster (Israel) Ltd.Inventors: Gal Hayam, Tal Haim Bar-on, Michael Maydel, Shiran Eliyahu, Wagdi Hani Hagla, Aharon Turgeman

Publication number: 20220330877Abstract: A method for evaluation of electrical propagation in the heart includes receiving a pacing signal applied to a heart of a patient, the pacing signal including a sequence of normal and shorter, abnormal, pacing stimuli. A responsive cardiac signal is received, that is sensed by electrodes at a location in the heart and on the body surface of the patient. A model response is found and annotated from evoked potentials caused by the normal pacing stimuli. A correlation is made between the model response along the different signal sections to find and calculate a normal and decremental time delays between the pacing stimuli and respectively resulting evoked potentials at a tissue location. A time difference is calculated, between the normal time delay and the decremental time delay. An EP map of at least a portion of the heart is presented to a user, with a graphical indication of the time difference presented at the tissue location.Type: ApplicationFiled: April 19, 2021Publication date: October 20, 2022Inventors: Tal Haim Bar-on, Meir Bar-Tal, Gal Hayam, Einat Shapira
