May refine ambulatory HRV interpretation in healthy subjects; leaves open relevance to cardiovascular disease cohorts.
Observational (n=5)
p-value: p=<0.05
Long-term heart rate variability exhibits circadian and ultradian rhythms that are synchronized with body movements but are not solely driven by physical activity.
Aoyagi et al. (2000) conducted an observational in Healthy (n=5). Body movement was evaluated on Coherent relationships between body movement and heart rate variability (p=<0.05). Body movement in healthy subjects showed persistent oscillations synchronized with long-term heart rate variability at ultradian and circadian frequencies (P<0.05 for coherence).
