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.

Cardiac mapping using a 3D grid

Methods and systems for the determination and representation of anatomy anatomical information are disclosed herein.

Impedance based anatomy generation

Methods and systems for determining the position of an object, such as tracking the position of one or more catheters in a patient's heart cavity are disclosed herein.

Tracking using field mapping

Methods and systems for the determination and representation of a chamber anatomy are disclosed herein.

Methods and systems for the determination and representation of anatomy anatomical information are disclosed herein. Methods and systems described herein include generating anatomical information about the heart based on positions of the catheter electrodes and the electrical signals from the electrodes at the determined subset of electrode positions.

Methods and systems for determining whether a location of multiple current injecting electrodes has changed are disclosed herein.

Electrode displacement determination

Methods and systems for determining anatomical information based on signals measured by multiple, spatially distributed electrodes on a catheter are disclosed herein. In some examples, methods and systems disclosed herein can include causing current to flow between at least some of the electrodes, measuring an electrical signal at each of one or more measuring electrodes, and determining anatomical information based on the measured signals.

Methods and systems for the determination and representation of anatomical information are disclosed herein. In some examples, methods described herein can include determining a boundary of at least a portion of the heart based on measured electrical signals, determining an area of the boundary corresponding to an endocardial boundary, and displaying a portion of the boundary of the heart with the display including a visual indicia indicative of the determined area of the boundary.
