Patent number: 11273302Abstract: A method includes acquiring a bipolar signal from a first electrode and a second electrode contacting a first location and a second location, respectively, in a heart of a living subject. The method further includes acquiring a unipolar signal from the first electrode while in contact with the first location, and deriving from the bipolar signal and the unipolar signal a point in time at which the first location is generating the unipolar signal. The method also includes computing a metric for a conduction velocity of the unipolar signal at the first location based on a shape of the unipolar signal at the point in time.Type: GrantFiled: December 10, 2019Date of Patent: March 15, 2022Assignee: Biosense Webster (Israel) Ltd.Inventors: Lior Botzer, Amir Ben-Dor, Yoram Chmiel, Aharon Turgeman, Liron Shmuel Mizrahi, Noga Salomon, Galia Givaty

Patent number: 9883918Abstract: While detecting a cardiac arrhythmia, a mapping electrode of a probe is used to associate a local activation time with a first location in a region of interest in the heart. While detecting an absence of the cardiac arrhythmia, the local activation time is associated with a second location in the heart. Electrical data of the first location is assigned to the second location, and an electroanatomic map of the heart is generated that includes the second location in association with the assigned electrical data of the first location.Type: GrantFiled: March 21, 2017Date of Patent: February 6, 2018Assignee: Biosense Webster (Israel) Ltd.Inventors: Yoram Chmiel, Gal Hayam

Patent number: 8577450Abstract: Methods and systems for mapping cardiac electrical activity employ a cardiac catheter having a plurality of spines mounted at the distal end, each spine having a plurality of electrodes. Electrical signal data are obtained from the heart via the electrodes, and respective intracardiac locations and orientations of the spines are sensed. An electroanatomic map of the heart is derived from the signal data, and presented as a graphic representation of the respective intracardiac locations and orientations of the spines, with distinctive graphical indicia of at least portions of the spines. The method is further carried out by displaying the electroanatomic map, and responsively to the displayed electroanatomic map, adjusting at least one of the locations and orientations of at least one of the spines.Type: GrantFiled: July 23, 2012Date of Patent: November 5, 2013Assignee: Biosense Webster (Israel) Ltd.Inventors: Yoram Chmiel, Jaron Breitman, Gal Hayam
