Abstract
Described embodiments include a system that includes an electrical interface and a processor. The processor is configured to receive, via the electrical interface, an electrocardiographic signal from an electrode within a heart of a subject, to ascertain a location of the electrode in a coordinate system of a computerized model of a surface of the heart, to select portions of the model responsively to the ascertained location, such that the selected portions are interspersed with other, unselected portions of the model, and to display the model such that the selected portions, but not the unselected portions, are marked to indicate a property of the signal. Other embodiments are also described.
Claims20
A system for enhancing anatomical mapping by indicating electrical properties of the surface of the anatomy, comprising:
- an electrical interface;
- and
- a processor, configured to:
- receive, via the electrical interface, a first electrocardiographic signal from a first electrode and a second electrocardiographic signal from a second electrode within a heart of a subject,
- ascertain a property of each of the first and second signal,
- ascertain locations of the first and second electrodes in a coordinate system of a computerized model of the anatomical features of a surface of the heart,
- select portions of the model responsively to the ascertained locations, such that the selected portions are interspersed with other, unselected portions of the model by projecting a plurality of rays from each of the ascertained locations and selecting the portions of the model in response to the points at which the rays intersect the model;
- and
- display the model such that for each of the first and second electrodes, the portions of the model selected for each electrode are marked to indicate a corresponding property of the signal that was received from the corresponding electrode.
