目前对心房颤动(简称房颤)机制的基本认识有①局灶起源机制;②多子波折返机制;③主导折返环机制。以这些机制为指导的消融治疗房颤,存在消融时间长、并发症多,且成功率不高的缺点。因此,人们在不断地探索新的标测方法。由于各个研究中心所采取的标测方法和技术不同,出现以复杂碎裂心房电图区、房颤巢、主频点以及心脏神经丛为消融靶点的治疗方法。这些方法均取得了较好的疗效,又对房颤的机制有了更深入的认识。从所有方法标测的部位上看,似乎这些方法均有联系,均与心脏神经丛关联。如果能透过这些现象认识到房颤的本质,那么就有可能找到消融治疗房颤的简单方法。
At present, the basic understanding of the mechanism of atrial fibrillation (referred to as atrial fibrillation) are: ① focal origin mechanism; ② multiple wavelet return mechanism; ③ dominant reentrant ring mechanism. Ablation treatment of atrial fibrillation guided by these mechanisms has the shortcoming of a long time of ablation, many complications and a low success rate. Therefore, people are constantly exploring new mapping methods. Due to different mapping methods and technologies adopted by various research centers, the treatment methods of complex fragmented atrial electrogram area, atrial fibrillation nest, dominant frequency point and cardiac nerve plexus as ablation targets appear. These methods have achieved good results, but also a more in-depth understanding of the mechanism of atrial fibrillation. It seems that all these methods are related to the mapping of all the methods and are related to the cardiac plexus. If you can recognize the essence of atrial fibrillation through these phenomena, then it is possible to find a simple method of ablation of atrial fibrillation.
