Implication

Photoplethysmography may capture sympathetic oscillations more sensitively than HRV; Level 5 evidence leaves open clinical utility.

Structured PICO

Does photoplethysmography reveal different power spectrum characteristics of spontaneous fluctuations in peripheral circulation compared to heart rate variability?

Intervention

Photoplethysmography (PPG) for assessment of blood volume in tissue and systolic blood volume increase

Comparator

Heart rate variability (measured by photoplethysmographic period variability)

Outcome

Power spectrum of spontaneous fluctuations (low and high frequency oscillations)surrogate

Photoplethysmography reveals that low-frequency oscillations, attributed to sympathetic activity, are more pronounced in peripheral blood volume measurements than in heart rate variability.
