electroanatomical mapping
A technique that creates three-dimensional maps of cardiac chambers combining electrical and anatomical information during EP procedures.
Full Definition
Electroanatomical mapping is an advanced catheter-based technique that creates detailed three-dimensional reconstructions of cardiac chambers while simultaneously recording electrical activity from multiple points. Systems like CARTO and NavX integrate catheter position data with intracardiac electrograms to generate color-coded activation maps, voltage maps, and propagation maps. This technology enables precise localization of arrhythmia circuits, identification of scar tissue, and accurate guidance of ablation catheters. Electroanatomical mapping has revolutionized complex ablation procedures by providing real-time visualization of cardiac anatomy and electrical activity.
