Electroanatomic mapping is a method of creating a three dimensional model of the human heart during clinical cardiac electrophysiology procedures.
In addition to 3-D structure, the voltage and timing of signals at each point of the heart is recorded to generate different maps to understand and treat different rhythm disturbances.
[2] The system is designed to visualise the real-time calculated position and orientation of a specialised RF ablation catheter within the patient's heart in order to minimise radiation exposure during fluoroscopy, increase the accuracy of targeted RF ablation and reacquisition of pacing sites for re-ablation.
[3] Its navigation system calculates the position and orientation of the catheter tip, using three known magnetic sources as references.
[2] St. Jude Medical, now a part of Abbott, manufactures EnSite family of cardiac mapping systems, the latest edition being EnSite Precision, which allows speedy heart mapping during catheter ablation with better accuracy to be able to treat cardiac rhythm disturbances.
