Why the study?
The relation between preoperatively measured heart rate variability and intra- and postoperative complications was sparsely studied and last reviewed in 2007.

May aid preoperative risk stratification; extends HRV data yet heterogeneity precludes practice change.
Does preoperative heart rate variability predict intra- and postoperative complications in surgical patients?
Preoperative HRV indices show promise in predicting intraoperative hypotension and postoperative atrial fibrillation, though current evidence is limited by methodological heterogeneity.
Frandsen et al. (2022) studied this question.
