LOCAL ECG ANNOTATION VISUALIZATION

Methods and systems for electrophysiological measurement involve obtaining signals that indicate cardiac electrical activity by using electrodes in contact with the body tissues of a living patient. These signals are then processed to identify local activation times at the electrodes. The identified local activation times are displayed as traces representing the signals over time on a display screen. The brightness of specific trace segments within a designated time window, encompassing the identified local activation times, may be increased relative to segments outside the time window. The method provides flexibility in signal acquisition, allowing for the use of intracardiac electrogram signals acquired within the heart or electrocardiogram signals acquired from the body surface. This method enhances visibility and enables efficient analysis of cardiac activity traces for diagnostic and monitoring purposes.
