Atrial fibrillatory cycle length serves as an important predictor of atrial fibrillation complexity and the ease of termination via catheter ablation.
Atrial fibrillatory cycle length is inversely associated with the number of sources participating in AF maintenance observed in the computer model. In addition, AFCL is an important predictor of baseline duration of the arrhythmia, type of AF, and ease of catheter ablation therapy to terminate AF.
Haissaguerre et al. (Wed,) studied this question.
