Abstract: A medical apparatus includes a probe configured for insertion into a body of a patient. The probe includes electrodes configured to contact tissue of a region within the body. The apparatus further includes a display screen, a position-tracking system configured to acquire position coordinates of the electrodes within the body, and a processor. The processor is configured to acquire electrophysiological signals from the electrodes while they are held stationary in the region, extract electrophysiological parameters from the signals, compute a measure of consistency of the parameters, and render to the display screen a three-dimensional (3D) map of the tissue while superimposing on the map, responsively to the position coordinates, a visual indication of the extracted parameters at the locations for which the measure of consistency satisfied a consistency criterion, and automatically discarding from the map the parameters for which the measure of consistency did not satisfy the consistency criterion.

Abstract: A system for electrophysiological measurement includes a probe having a distal end configured for insertion into a body cavity of a living subject and including an array of electrodes that are disposed along the distal end and are configured to contact tissue at multiple locations within the body cavity. A processor is configured to acquire signals from the electrodes over a period of time during which the probe moves within the body cavity, to compute, in response the signals, metrics that are indicative of a respective quality of contact between each of the electrodes and the tissue over the period of time, and to output an indication of the metrics to a user of the system.

Abstract: A method includes receiving multiple electrophysiological (EP) signals acquired by multiple electrodes of a multi-electrode catheter that are in contact with tissue in a region of a cardiac chamber, and respective tissue locations at which the electrodes acquired the EP signals. The region is divided into two sections. Using the EP signals acquired by the electrodes, local activation times (LAT) are calculated for the respective tissue locations, and found are: a first section of the two sections having a smaller average LAT value, and a second section of the two sections having a higher average value. Determined are a first representative location in the first section, and a second representative location in the second section. A propagation vector is calculated between the first and second representative locations, that is indicative of propagation of an EP wave that has generated the EP signals. The propagation vector is presented to a user.
