AI Technical Summary
In ablation procedures, identifying end-expiratory difficulties within a short period of time is challenging, especially when high-energy ablation is applied. Respiratory movements make it difficult to track catheter position, and existing technologies struggle to accurately identify end-expiratory location in high-noise environments.
By identifying the initial end-expiratory phase before ablation, the catheter velocity is determined, and the end-expiratory phase during ablation is identified when the catheter velocity is less than a predetermined velocity and the estimated end-expiratory position is less than a predetermined distance from the initial end-expiratory position. The end-expiratory phase is identified using catheter position data, independent of respiratory indication values.
It enables accurate identification of end-expiratory position in high-noise and high-energy ablation environments, improving the precision and stability of ablation surgery and reducing the dependence of respiratory data on noise interference.
