Does heart rate variability predict the recurrence of atrial fibrillation in patients after electrical cardioversion?
Increased heart rate variability, particularly in high-frequency and very-low-frequency bands, predicts early and late recurrence of atrial fibrillation after electrical cardioversion.
Vikman et al. (2003) studied this question.
