Detection of focal source and arrhythmogenic substrate from body surface potentials to guide atrial fibrillation ablation
Fig 8
Kaplan–Meier curves of two paroxysmal AF patient groups, showing the post-ablation AF-free likelihoods up to three years.
The grouping was according to whether the AF episodes in the patient were predicted as driven by initiator-type FS originating from a single atrium. The shading shows the 95% confidence interval of the Kaplan–Meier curves. The first group had better two-year and three-year AF-free outcomes than the other group, with p-values of logrank tests both < 0.01. n.u.: normalized unit.
