Abstract

In cardiac ablation procedures, the accuracy of catheter positioning determines the authenticity of the cardiac model and the accuracy of the ablation target. This article reviews the literature on catheter positioning in electrophysiology and summarizes the key technologies for catheter positioning, such as magnetic-electric fusion and interference suppression. Addressing the limitations of electric and magnetic positioning individually, the paper elaborates on the rationale for catheter positioning technology based on magnetic-electric fusion. It also outlines the framework of a complex catheter positioning system. Specifically, the magnetoelectric conversion matrix is established first, followed by the optimization of the catheter shape. The interference factors such as magnetic field interference, body movement, respiration, and heartbeat in catheter positioning and their suppression methods are analyzed and discussed in detail. Finally, the development trend of three-dimensional electrophysiology catheter positioning technology is prospected, offering feasible insights for the research on catheter positioning technology based on magnetic-electric fusion.

[基于磁电融合的三维电生理导管定位关键技术]。

在心脏消融术中，导管定位的准确性决定了心脏模型的真实性和消融术靶的准确性。本文综述了电生理学中导管定位的相关文献，总结了导管定位的关键技术，如磁电融合、干扰抑制等。针对电定位和磁定位各自的局限性，阐述了基于磁电融合的导管定位技术的基本原理。它还概述了一个复杂的导管定位系统的框架。具体而言，首先建立磁电转换矩阵，然后对导管形状进行优化。详细分析和讨论了导管定位过程中磁场干扰、身体运动、呼吸、心跳等干扰因素及其抑制方法。最后，展望了三维电生理导管定位技术的发展趋势，为基于磁电融合的导管定位技术的研究提供了可行的见解。
