    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 and method for voltage-guided anatomical shell editing includes outputting, to a display device, an anatomical shell of a cardiac structure. The anatomical shell is based on signals sensed by a mapping probe, each signal including a respective sensed voltage. User input specifying a first target depth for editing is received, as is a selection of a first region of the anatomical shell. A modified anatomical shell is generated by removing a first portion of the anatomical shell including the selected first region to a first editing depth based on the first target depth and generating a new surface region on the modified anatomical shell. Based on the voltage associated with the new surface region, the edit can be maintained, undone, and/or modified.

    Abstract: A system includes a display device configured to present a cardiac map; and a processing unit configured to: receive electrical signals; generate the cardiac map; and facilitate display of the cardiac map, where each electrical signal corresponds to a map location. The processing unit is also configured to receive a user selection of a selected portion of the cardiac map, the selected portion including a set of map locations, each of the set of map locations corresponding to an electrical signal of a set of signals that is a subset of the received electrical signals. The set of map locations has a first spatial arrangement and the processing unit is configured to facilitate display of a set of electrical signal representations, each representation corresponding to one of the set of electrical signals, the set of electrical signal representations having a second spatial arrangement, which corresponds to the first spatial arrangement.
