    Abstract: A system for providing information about a patient's heart includes one or more electrodes that receive signals from electrical activity of the heart over one or more heart beat cycles. The system is characterized by an electronic processor coupled to the one or more electrodes to: receive the signals from the one or more electrodes; execute an automated set-up routine that processes the signals to automatically provide at least some set-up results for new mapping configurations; and/or process the signals with beat detection and beat acceptance criteria for new or existing mapping configurations to provide information about how well the signals match one or more of the new or existing mapping configurations.

    Abstract: A system for facilitating display of cardiac information includes a display device configured to present a cardiac map; and a processing unit configured to: receive electrical signals and indications of measurement locations corresponding to the electrical signals; generate, based on the electrical signals, the cardiac map, which includes annotations representing cardiac signal features; and determine a set of interesting cardiac signal features. The processing unit also may determine, based on the set of interesting cardiac signal features, a region of interest; and facilitate display, via the display device, of the cardiac map and a representation of the region of interest. The representation of the region of interest includes a first display parameter value that is different from a second display parameter value, where the second display parameter value is associated with at least one cardiac signal feature that is not included within the region of interest.

    Abstract: A system for facilitating display of cardiac mapping information includes a catheter having one or more electrodes that measure electrical signals in the heart, and a processing unit. The processing unit receives the electrical signals from the catheter and receives an indication of a measurement location corresponding to each signal. The processing unit extracts a set of features from the signals, where each feature includes a value corresponding to a metric. A three-dimensional grid is constructed, wherein each node of the grid corresponds to a physical point in three-dimensional space. The system identifies a set of electrical signals in a neighborhood associated with a node; determines, based on the set of features extracted from the set of electrical signals, a node value; associates the node value with the node; and facilitates presentation of a map corresponding to a cardiac surface based on the node value.

    Abstract: Methods and systems for mapping and displaying cardiac structures are disclosed. The method includes sensing cardiac electrical signals at a plurality of points and generating a cardiac map of at least a portion of one or more cardiac structures based on at least a portion of the sensed cardiac electrical signals. A surface map having a corresponding first position relative to the cardiac map is generated. The surface map includes a first surface point, where a first cardiac electrical signal feature is represented on the surface map at the first surface point if a corresponding first cardiac electrical signal is sensed at a point that is located within a threshold distance of the first surface point. The cardiac map and the surface map, at the first position, are displayed. The surface map may be repositioned to a second position.

    Abstract: A system for providing information about a patient's heart, the system including one or more catheters that receive intracardiac signals from electrical activity of the heart over one or more heart beat cycles and an electronic processor coupled to the one or more catheters. The electronic processor to: receive the intracardiac signals from the one or more catheters; preprocess the intracardiac signals to provide preprocessed signals, wherein each of the intracardiac signals is preprocessed to provide a corresponding preprocessed signal; and compare the preprocessed signals to a set of signals to determine a degree of similarity between each of the preprocessed signals and the set of signals.

    Abstract: Systems and methods for facilitating processing of cardiac information based on sensed electrical signals include a processing unit configured to receive a set of electrical signals; receive an indication of a measurement location corresponding to each electrical signal of the set of electrical signals; and generate, based on at least one of an annotation waveform corresponding to each electrical signal of the set of electrical signals and a set of annotation mapping values, an annotation histogram.
