摘　　要：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 solve the problem that the existing mapping system fails to obtain the threedimensional electroanatomical information from the combined endocardial and epicardial mapping in clinical diagnosis and mechanism research of such complex arrhythmia as atrial fibrillation, ventricular tachycardia and ventricular fibrillation, this paper designed a scheme to develop a new combined threedimensional mapping system so as to meet the special requirements of complex arrhythmia. MethodsFrom the clinical practice, based on the principle of magnetic field orientation and magnetic localization software, this system realized multi-point synchronous magnetic localization of magnetic catheters.And based on three-dimensional reconstruction technology, image and information fusion technology,using topological mapping method and epicardial partition technique, this system established threedimensional endocardial, epicardial and their common electro-anatomical mapping. Results According to the preliminary results from animal experiment, the designed new three-dimensional mapping system may combine endocardial and epicardial mapping to meet the specific needs of clinical diagnosis and mechanism research of complex arrhythmia. Conclusion The new mapping system provided a new idea for clinical diagnosis and mechanism research of complex arrhythmia.
