Spectral Analysis of Photoplethysmography Signal in Patients with Cardiovascular Diseases and Healthy Subjects
2021 5th Scientific School Dynamics of Complex Networks and their Applications (DCNA)(2021)
Abstract
this study presents the results of the spectral analysis of the photoplethysmographic signals obtained from the healthy subjects and the patients with early pre-clinical stages of arterial hypertension, coronary artery disease, and aortic valve stenosis patients. The normalized power density of the low-frequency (LF%) oscillations is significantly higher in the cardiovascular patients, while the n...
