Cardiac mapping using a 3d grid

A method for facilitating display of cardiac mapping information, the method comprising:

• receiving a plurality of electrical signals from a mapping catheter;
• receiving an indication of a measurement location corresponding to each of the plurality of electrical signals;
• extracting at least one feature from each of the plurality of electrical signals, wherein the at least one feature comprises at least one value corresponding to at least one metric;
• constructing a three-dimensional grid having a plurality of nodes, wherein each of the plurality of nodes corresponds to a physical point in three-dimensional space;
• identifying a set of electrical signals in a neighborhood associated with a node, wherein each of the set of electrical signals in the neighborhood has a corresponding measurement location that is located within a predetermined distance of the node;
• aggregating the set of features extracted from the set of electrical signals;
• determining, based on the aggregated set of features extracted from the set of electrical signals, a node value;
• associating the node value with the node;
• and
• facilitating presentation of a map corresponding to a cardiac surface and based on the node value.

One or more computer-readable media having computer-executable instructions embodied thereon for facilitating display of cardiac mapping information, the computer-executable instructions configured to cause a processor, upon being executed by the processor, to instantiate at least one component, the at least one component comprising:

• a feature extractor configured to extract at least one feature from each of the plurality of electrical signals, wherein the at least one feature comprises at least one value corresponding to at least one metric
• a grid generator configured to construct a three-dimensional grid having a plurality of nodes, wherein each of the plurality of nodes corresponds to a physical point in three-dimensional space;
• an aggregator configured to:
• identify a set of electrical signals in a neighborhood associated with a node, wherein each of the set of electrical signals in the neighborhood has a corresponding measurement location that is located within a predetermined distance of the node;
• determine, based on the set of features extracted from the set of electrical signals, a node value;
• and
• associate the node value with the node;
• and
• an interpolator configured to facilitate presentation of a map corresponding to a cardiac surface by performing an interpolation based on the node value to determine a mapping value.
