Patent number: 11589795Abstract: 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: GrantFiled: December 22, 2020Date of Patent: February 28, 2023Assignee: Biosense Webster (Israel) Ltd.Inventors: Refael Itah, Natan Sharon Katz, Yaron Kadoshi, Gal Hayam, Elad Nakar, Tal Haim Bar-on, Eliyahu Ravuna, Lior Botzer, Yoav Benaroya, Nuno Miguel Rocha Cortez-Diaz
