Meanings of derive prv in English

The objective is to evaluate if video- derived PRV indexes may replace HRV in the assessment of autonomic responses to external stimulation.

However, despite these differences video- derived PRV indexes were able to evince the autonomic responses expected by the sympathetic stimulation induced by the rest-to-stand manoeuvre.

These results provide evidence that some differences exist between variability indexes extracted from HRV and video- derived PRV, mainly in the HF band during standing.
