Abstract: At least some embodiments of the present disclosure is directed to a method of processing cardiac information. The method includes the steps of: receiving an activation waveform comprising a set of activation waveform data; receiving a range of window size. For each of the plurality of window sizes, the method further includes the steps of: selecting a position of a central window; calculating a set of backward correlations; calculating a set of forward correlations; determining a backward confidence value based on the set of backward correlations; and determining a forward confidence value based on the set of forward correlations. Additionally, the method includes the steps of: comparing the set of confidence values to select a designated confidence value and a selected window size corresponding to the designated confidence value; and determining a local cycle length based on the selected window size.

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 processing cardiac information include a processing unit configured to receive a set of cardiac electrical signals; receive an indication of a measurement location corresponding to each of the set of electrical signals; and identify, for each electrical signal of the set of electrical signals, a deflection. The deflection includes a deviation from a signal baseline. An activation waveform corresponding to the set of electrical signals is generated based on the identified deflections.

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.
