心房颤动（房颤）的治疗仍是一个挑战。尽管电生理学家知道许多治疗房颤的策略，但其潜在机制仍然大部分未知。此外，阵发性和长期持续性房颤的最佳消融策略尚不清楚。复杂碎裂心房电图（CFAE）在消融策略中变得越来越重要，特别是对于长期持续性AF。CFAE的自动检测和信号分析对于在消融过程中支持医生至关重要。Nguyen、Schilling和多塞尔等人提出的CFAE定位算法为CFAE的后处理和信号分析奠定了良好的基础。它采用非线性能量算子结合阈值。在本文中，这种新的算法进行了测试的临床数据和临床接受的算法相比。
The curative therapy of atrial fibrillation (AF) is still challenging. Although the electrophysiologists know many strategies to cure AF, the underlying mechanisms are still mostly unknown. Also the optimal ablation strategy for paroxysmal and long-lasting persistent AF is not known. Complex fractionated atrial electrograms (CFAEs) are becoming more and more important in the ablation strategies, especially for longlasting persistant AF. Automated detection and signal analysis of CFAEs is essential in supporting the physicians during the ablation procedure. The robust algorithm to locate CFAEs presented in the contribution by Nguyen, Schilling and Dossel delivers a good bases for postprocessing and signal analysis of CFAEs. It is employing a non-linear energy operator combined with thresholding. In this paper this new algorithm is tested on clinical data and compared to clinically accepted algorithms.
