Why the study?
Autonomic dysfunction plays an important role in cardiovascular pathology, but the spectral indices of photoplethysmographic signals and their age-related dynamics needed evaluation for cardiovascular screening.
Does spectral analysis of photoplethysmographic signals detect autonomic dysfunction in patients with cardiovascular diseases compared to healthy individuals?
Does spectral analysis of photoplethysmographic signals detect autonomic dysfunction in patients with cardiovascular diseases compared to healthy individuals?
Spectral analysis of photoplethysmographic signals reveals distinct patterns of autonomic dysfunction in patients with cardiovascular diseases, suggesting its potential utility as a screening tool in preventive medicine.
Spectral PPG analysis may detect autonomic shifts in hypertension and CAD; leaves open diagnostic standardization and outcome links.
