rotor mapping
Advanced mapping technique identifying spiral wave reentrant circuits driving persistent atrial fibrillation.
Full Definition
A sophisticated electrophysiologic mapping technique designed to identify rotor-based reentrant circuits that may serve as drivers of persistent atrial fibrillation. Rotor mapping utilizes specialized catheters with multiple electrodes to record simultaneous electrical activity from large atrial areas, with computational algorithms identifying spiral wave patterns and phase singularities. The technique aims to locate stable rotational circuits that maintain fibrillation, providing targeted ablation sites beyond traditional pulmonary vein isolation. Clinical validation remains ongoing, with varying success rates reported across different mapping systems and patient populations. Proper documentation requires detailed description of rotor locations, stability, and correlation with clinical outcomes.
