Pfa reference electrode automatic matching method and system based on magnetic navigation flexible catheter
By dividing the reference electrode array on the body surface into zones and matching the position of the ablation electrode using a three-dimensional coordinate system, the target reference electrode is dynamically selected to construct the ablation circuit. This solves the problems of uneven ablation effect and non-optimal energy direction in PFA unipolar catheter ablation, thus improving the efficiency and effectiveness of ablation treatment.

AI Technical Summary
In existing PFA monopolar catheter ablation technology, the reference electrode placement method leads to uneven ablation effects, non-optimized energy direction, and poor comparability of multi-target ablation, affecting the short- and long-term effects and operational efficiency of ablation treatment.
Based on a magnetically guided flexible catheter, the target reference electrode is dynamically selected to construct a pulsed electric field ablation circuit by dividing the body surface reference electrode array into zones and using a three-dimensional coordinate system to match the real-time position of the ablation electrode, thereby optimizing the energy distribution and direction.
It significantly shortens the current path length, reduces energy dissipation, and improves the local strength and efficiency of the ablation electric field, achieving more stable and uniform through-wall damage.
