What are the normal reference values for heart rate variability parameters in children aged 6-8 years?
This study establishes unified reference values for heart rate variability parameters in children aged 6-8 years, demonstrating that 1-minute ECG recordings provide reliable data comparable to 5-minute recordings.
Seppälä et al. (2013) studied this question.
