Abstract
Interobserver reproducibility is high for time domain and power spectr al measures of heart rate variability, with greater reproducibility fo r low-frequency measures, and especially for the standard deviation of the 5-minute RR intervals over 24 hours, than for high-frequency meas ures, Overall interobserver variability of <8% for these measures is l argely (50% to 75%) explained by interobserver differences in annotati on of supraventricular ectopy and sinus arrhythmia.
