MARKING COMPUTERIZED MODEL OF CARDIAC SURFACE

摘要

To provide a system of displaying electroanatomical information.SOLUTION: Embodiments include a system 20 that includes an electrical interface 35 and a processor 28. The processor is configured to receive, via the electrical interface, an electrocardiographic signal from an electrode within the heart of a subject, to ascertain a location of the electrode in a coordinate system of a computerized model 22 of a surface of the heart, to select portions of the model responsively to the ascertained location, such that the selected portions are incorporated into 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.SELECTED DRAWING: Figure 1
