摘要： Electroanatomic mapping is carried out by inserting a multi-electrode probe into a heart of a living subject, recording electrograms from the electrodes concurrently at respective locations in the heart, delimiting respective activation time intervals in the electrograms, generating a map of electrical propagation waves from the activation time intervals, maximizing coherence of the waves by adjusting local activation times within the activation time intervals of the electrograms, and reporting the adjusted local activation times.

摘要： A method, including acquiring initial signals from selected positions in a heart, computing respective initial local values of a signal propagation metric at the selected positions, and interpolating the initial local values between the selected positions to compute initial interpolated values of the signal propagation metric at intermediate positions, between the selected positions. The method further includes acquiring subsequent signals from the positions, computing respective subsequent local values of the signal propagation metric at the selected positions, and spatially interpolating the subsequent local values of the signal propagation metric between the selected positions to compute subsequent interpolated values of the signal propagation metric at the intermediate positions. A map of the signal propagation metric is displayed, and when the subsequent interpolated values exceed a bound defined with respect to the initial interpolated values, an indication is provided on the map that the bound has been exceeded.

摘要： Apparatus, including a flexible insertion tube, having a distal segment that is configured to be inserted into a body organ. A plurality of elastic branches are connected to the distal segment of the insertion tube at different, respective locations and extend transversely away from the insertion tube at the respective locations. There are one or more respective electrodes disposed on each of the elastic branches and there are conductors traversing the elastic branches so as to couple the electrodes to the insertion tube.

摘要： A method, including recording parameters indicative of a quality of ablation performed at one or more sites in a region of a human heart, and receiving a set of electrophysiological signals indicative of a wave of electrical activation flowing through the region. The method further includes identifying locations within the region at which the wave is blocked from flowing and estimating confidence levels with respect to a blockage of the wave at the locations in response to the signals and the parameters. The method also includes displaying a map of the human heart including an indication of the confidence levels.
