Implication
Core cooling may modulate very low-frequency HRV; hypothesis-generating and should not yet change practice.
Structured PICO
Does core or skin-surface cooling modulate heart rate variability in human subjects?
P
Population
Human subjects
I
Intervention
Core temperature reduction via intravenous cold saline infusion, and skin-surface warming/cooling until shivering
O
Outcome
Heart rate variability (power spectral analysis in distinct band-widths)surrogate
Very low-frequency heart rate variability is modulated by thermal stimuli causing core hypothermia and thermoregulatory activity.
