May enhance HRV accuracy in complex arrhythmias; leaves open prospective validation before clinical adoption.
Which mathematical method best corrects RR-interval time series data to remove the impact of arrhythmias on heart rate variability indices?
Cubic splining with interpolation is the most effective method for correcting RR-interval data to accurately assess heart rate variability in the presence of complex arrhythmias.
Vybiral et al. (2002) studied Arrhythmias. RR-interval time series correction methods (constant RR, mean RR, cubic splining) vs. Uncorrected data or alternative methods was evaluated on Fidelity in restoring time and frequency domain indices of heart rate variability. Cubic splining with interpolation was the overall best technique for correcting RR-interval time series and overcoming undesired segments in data files with complex arrhythmias.
