Nonlinear HRV may aid postoperative AF risk stratification after CABG; leaves open prospective validation before clinical adoption.
Does nonlinear heart rate variability analysis predict postoperative atrial fibrillation in patients undergoing coronary artery bypass grafting?
Peak point correlation dimension, a nonlinear measure of heart rate variability, independently predicts postoperative atrial fibrillation after CABG, potentially allowing for targeted prophylaxis.
Chamchad et al. (2006) studied this question.
