The intensity of oscillations of the photoplethysmographic waveform variability at frequencies 0.04-0.4  Hz is effective marker of hypertension and coronary artery disease in males.

Conclusion: Frequency-domain indices of photoplethysmographic waveform variability (in particular, HF%, LF%, and LF/HF) are sufficiently sensitive and specific markers of hypertension and coronary artery disease in adult males. PMID: 31402715 [PubMed - as supplied by publisher]
