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.
