Why the study?
Do noninvasive AF complexity parameters derived from surface ECGs predict procedural outcome and long-term success of stepwise catheter ablation in patients with persistent AF?
Do noninvasive AF complexity parameters derived from surface ECGs predict procedural outcome and long-term success of stepwise catheter ablation in patients with persistent AF?
ECG-derived AF complexity parameters, particularly fibrillation-wave amplitude, perform at least as well as clinical parameters in predicting AF termination and long-term success of catheter ablation in persistent AF.

ECG-clinical models may refine expectations for persistent AF ablation success; hypothesis-generating pending prospective validation.
