Abstract: A system for generating an electrophysiological (EP) map includes a display and a processor. The processor is configured to (i) receive multiple EP data points comprising respective locations and EP values, generated from signals acquired by one or more electrodes of a catheter that are in contact with tissue of a cardiac chamber, (ii) score the received data points with respective quality scores, (iii) for a given unit volume of the EP map, select, from among the data points whose locations fall in the unit volume, a data point with a highest quality score, for use in generating the EP map, and (iv) visualize the EP map to a user, on the display.

Abstract: An interactive event timeline system and method are disclosed. Multiple events and/or signal indicators are captured during a medical procedure, such as a cardiac procedure. Event data relevant to the cardiac procedure may include, tags, user generated points, ablation events, pacing events and other like events. An interactive event timeline is generated from the captured events and displayed on a visual display device. The interactive event timeline is correlated with a vertical listing of the events and a selected event viewer. All three views may be displayed simultaneously. The interactive event timeline allows a physician or user (collectively “user”) to see temporal relationships between the captured events. The user can see, for example, simultaneous events, long duration events versus short duration events, continuous events and specific event types.

Abstract: A method, consisting of presenting on a display screen a graphical image of a heart of a patient, including icons representing a catheter that is positioned within the heart and an electrode on the catheter, while the electrode is in contact with tissue at a location in the heart. The method further includes acquiring, using the electrode, electrical signals from the tissue at the location, and processing the acquired signals so as to detect an occurrence of a predefined signal feature in the acquired signals. The method also includes, upon detecting the occurrence of the predefined signal feature, modifying a visual feature of at least one of the icon representing the electrode and the icon representing the catheter on the display screen.
