目的房颤、室速、室颤等复杂心律失常的临床诊治和机制研究需要获取心内膜、心外膜共同标测的三维电解剖信息,现有的标测系统无法实现。为满足这一特有需要,本文进行新型三维标测系统方案研究。方法该系统从临床实际需要出发,基于磁场定位原理,借助磁定位软件,实现磁导管的多点同步磁定位;基于三维重建技术、图像与信息融合技术,利用拓扑映射方法,结合心外膜分区技术,建立心内膜、心外膜及其共同标测的电解剖图。结果动物实验初步结果表明,设计的新型三维标测系统能够进行心内膜及对应区域心外膜标测,满足复杂心律失常的临床诊治及机制研究的特有需要。结论新型标测系统为复杂心律失常的临床诊治及机制研究开辟了新途径。
Objective To study the clinical diagnosis and mechanism of atrial fibrillation, ventricular tachycardia, ventricular fibrillation and other complex arrhythmia, and to obtain the three-dimensional electroanatomical information of endocardial and epicardial common mapping. The existing mapping system can not be realized. In order to meet this unique needs, this article carries out a new type of 3D mapping system program. Methods Based on the principle of magnetic field localization and the magnetic localization software, the system realizes the multi-point synchronous magnetic positioning of the magnetic catheter. Based on the three-dimensional reconstruction technology, the image and information fusion technology, the topological mapping method is used in combination with the epicardial partition Technology, the establishment of endocardium, epicardial and their common mapping of the electroanatomic map. Results The preliminary results of animal experiments showed that the new three-dimensional mapping system designed for endocardial and corresponding regional epicardial mapping to meet the clinical diagnosis and treatment of complex arrhythmias and the specific needs of the study. Conclusion The new mapping system opens up new avenues for clinical diagnosis and treatment of complex arrhythmia.
