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: 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.
