心房颤动(房颤)时心房电图会呈现特征性的复杂碎裂电图。多个研究认为复杂碎裂电图反映了局部折返激动,且与心脏自主神经兴奋有密切的关系。目前复杂碎裂电图指导临床射频消融治疗房颤已取得较高成功率,进一步证实复杂碎裂电图代表了房颤的基质。
Atrial fibrillation (atrial fibrillation) Atrial electrogram will present a characteristic complex fragmented electrogram. Several studies suggest that complex fragmented electrograms reflect partial reentry and are closely related to the excitement of cardiac autonomic nervous system. At present, the complex fragmented electric map guides clinical radiofrequency ablation of atrial fibrillation has achieved a higher success rate, further confirms the complex fragmented electrogram represents the matrix of atrial fibrillation.
