    摘要: An animated electrophysiology map is generated from a plurality of data points, each including measured electrophysiology information, location information, and timing information. The electrophysiology and location information can be used to generate the electrophysiology map, such as a local activation time, peak-to-peak voltage, or fractionation map. Animated timing markers can be superimposed upon the electrophysiology map using the electrophysiology, location, and timing information. For example a series of frames can be displayed sequentially, each including a static image of the electrophysiology map at a point in time and timing markers corresponding to the state or position of an activation wavefront at the point in time superimposed thereon. The visibility or opacity of the timing markers can be adjusted from frame to frame, dependent upon a distance between the timing marker and the activation wavefront, to give the illusion that the timing markers are moving along the electrophysiology map.

    摘要: A computer-implemented method includes storing location data for at least one invasive electrode that is movable within a patient's body. The method also includes storing electrophysiological measurement data representing the electrophysiological signals measured at the outer surface of a patient's body by body surface electrodes and within the patient's body by the at least one invasive electrode. The method also includes storing geometry data representing anatomy of the patient spatially, and locations of the respective body surface electrodes and the at least one invasive electrode in three-dimensional space. The geometry data for the at least one invasive electrode can vary based on movement of the at least one invasive electrode within the patient's body. The method also includes reconstructing electrophysiological signals on a surface of interest within the patient's body based on the electrophysiological measurement data and the geometry data.

    摘要: 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.
