Electroanatomical Mapping System
Computer-based technology that creates three-dimensional maps of cardiac chambers by correlating catheter position with electrical signals. Essential for complex ablation procedures.
Full Definition
Electroanatomical mapping systems are sophisticated computer platforms that integrate real-time catheter position tracking with electrical signal acquisition to create detailed three-dimensional reconstructions of cardiac chambers. These systems use magnetic field technology, impedance-based localization, or hybrid approaches to precisely track catheter movement within the heart. The resulting maps display electrical activation patterns, voltage amplitudes, and anatomical structures, allowing operators to identify arrhythmia substrates and plan targeted ablation strategies. Modern systems also integrate imaging data and provide features such as catheter stability monitoring and lesion tagging. Popular systems include CARTO, EnSite, and Rhythmia mapping platforms.
Usage
Usage note: Often referred to by brand names like CARTO or EnSite. Essential technology in modern EP labs.
