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.

摘要： Disclosed are various examples and embodiments of systems, devices, components and methods configured to detect a location of a source of at least one cardiac rhythm disorder in a patient's heart. In some embodiments, electrogram signals are acquired from inside a patient's heart, and subsequently normalized, adjusted and/or filtered, followed by generating a two-dimensional (2D) spatial map, grid or representation of the electrode positions, processing the amplitude-adjusted and filtered electrogram signals to generate a plurality of three-dimensional electrogram surfaces corresponding at least partially to the 2 D grid, one surface being generated for each of selected discrete times, and processing the plurality of three-dimensional electrogram surfaces through time to generate a velocity vector map corresponding at least partially to the 2 D grid. The resulting velocity vector map is configured to reveal the location of the source of the at least one cardiac rhythm disorder, which may be, by way of example, an active rotor in a patient's myocardium and atrium.

摘要： A method includes receiving a cardiac signal that is sensed by electrodes at a location in a heart of a patient, the cardiac signal including signal components evoked by respective activations. The signal components in the cardiac signal are found and annotated. Respective time differences are calculated between the annotations and the corresponding activations. Based on the time differences, one or more cardiac tissue locations are identified, that demonstrate progressively slowing activation (PSA). An EP map of at least a portion of the heart is presented to a user, including providing a graphical indication of the one or more tissue locations that demonstrate the PSA.
