Implication

Hypothesis-generating for VLF as marker of delayed mental stress recovery; prospective studies needed before clinical adoption.

Structured PICO

Does a mental stress task cause a delayed recovery in the very low-frequency band of heart rate variability in healthy young subjects?

P
Population
19 healthy, young subjects
I
Intervention
Mental stress task (Stroop color word task for 20 min)
C
Comparator
Baseline resting state (10 min rest prior to the task)
O
Outcome
Changes in the very low-frequency (VLF) band of heart rate variability during the 120-minute recovery periodsurrogate

The very low-frequency band of heart rate variability exhibits a slow recovery following mental stress, which may help explain its association with cardiovascular disease prevention.
