Novel automated atrial pacemapping technique based on intracardiac pattern matching to identify the location of ectopic atrial activity.

Atrial ectopy from the pulmonary veins and non-pulmonary vein foci can trigger atrial fibrillation. In addition, the elimination of atrial ectopy is important to prevent recurrence. The intracardiac pattern matching technique has been reported as a useful method to manually visualize the location of triggers regardless of their frequency. We combined the original intracardiac pattern matching method with the automapping setting of CARTO CONFIDENCE and discovered the automated atrial pacemapping technique. We report two cases in which this technique was used to eliminate the atrial triggers. This technique achieved a time reduction and high-resolution mapping.
