The EnSite NavX Navigation and Visualization Technology aids easy and resourceful procedures by creating handy cardiac models or geometries, which display voltage data and activation timing to identify arrhythmias. This guides accurate catheter movement. The standard EP catheter electrodes sense the electrical indicators sent out between the Ensite NavX electrode patches. The Ensite System accumulates electrical data and information from the catheters. This information is used to navigate or track their movement and create 3-D (three-dimensional) representations of the chamber.
