摘要： A method includes receiving locations of multiple ablation sites formed on a surface of a heart. Distances are measured among at least some of the ablation sites based on the locations. One or more gaps between the ablation sites, which meet an alerting criterion, are identified. The identified gaps are indicated to an operator.

摘要： A method, including selecting an initial set of electrocardiograph (ECG) signals taken over a single heartbeat of a human subject, the set having respective morphologies to be used as a template for an arrhythmia of the subject, and receiving a subsequent set of ECG signals taken over a subsequent heartbeat of the human subject. The method also includes performing a cross-correlation between the initial set and the subsequent set, so as to generate a correlation coefficient that is a measure of a goodness of fit between geometries of the initial set and the subsequent set, and, when the correlation coefficient exceeds a threshold coefficient, accepting the subsequent heartbeat as having been caused by the arrhythmia.

摘要： One embodiment includes a cardiac ablation system, including an ablation probe including at least one ablation application element to ablate tissue in a chamber of a heart of a living subject, a tracking module to track a position of the at least one ablation application element within the heart, a memory to store a map of the chamber of the heart and store a different, respective default ablation-parameter set for each different region of the chamber, and processing circuitry to segment the map of the chamber into the different regions, receive a user input indicative of commencement of an ablation procedure, identify, responsively to the tracked position, a region of the chamber with which the at least one ablation application element is in contact, retrieve the respective default ablation-parameter set assigned to the identified region, and apply the retrieved default ablation-parameter set in controlling the ablation procedure.

摘要： A method including processing electrocardiograph (ECG) signals taken over a heartbeat received over a plurality of channels, selecting a subset of the ECG signals captured at a point in time with a window of interest (WOI) around reference annotations and having a morphology pattern within the WOI, storing the morphology patterns, receiving continuous sets of ECG signals taken over a plurality of heartbeats over the plurality of channels and having a morphology pattern within the WOI, performing a correlation between the stored morphology patterns of the ECH signals and the morphology patterns of the continuous sets of ECH signals for each heartbeat, generating a correlation coefficient that is a measure of a goodness of fit between geometries of the ECG signals and the continuous sets of ECG signals and identifying each heartbeat having a correlation coefficient that exceeds a threshold coefficient as having been caused by an arrhythmia.
