碎裂电位(CFAE)代表连续碎裂的心房激动,即2个或2个以上波折的心房波在基线上下连续碎裂曲折超过10s或平均周长≤120ms。它主要集中于肺静脉、左房前壁、间隔部、冠状窦、左房顶部和左后间隔二尖瓣峡部,机制可能与自主神经、主频率、心房颤动(简称房颤)周长、组织异质性和电压等相关。传统CARTO和NAVIX系统CFAE标测具有良好的稳定性,可用于指导消融治疗。是否进行单纯CFAE消融治疗房颤存在争议,但在传统消融策略上附加CFAE消融可以提高房颤消融的成功率,尤其持续性房颤。
Fragmentation potential (CFAE) represents a continuous fragmentation of the atrial activation, that is, two or more than two waves of atrial wave continuous fracture above the baseline fold more than 10s or average circumference ≤ 120ms. It is mainly concentrated in the pulmonary veins, anterior wall of the left anterior chamber, the septum, the coronary sinus, the left atrium and the left posterior septal mitral isthmus. The mechanism may be related to the autonomic nervous system, the main frequency, the perimeter of atrial fibrillation Quality and voltage related. Traditional CARTO and NAVIX system CFAE mapping has good stability, can be used to guide the ablation treatment. Whether a simple CFAE ablation of atrial fibrillation is controversial, but in addition to the traditional ablation strategy CFAE ablation can improve the success rate of atrial fibrillation ablation, especially persistent atrial fibrillation.
