Abstract
Aim. To analyze literature data on use of photoplethysmography (PPG) at the outpatient stage for remote monitoring of heart rate, arrhythmias, blood pressure (BP), temperature, respiratory rate.Research design. The search was carried out using the PubMed/Medline, Web of Science, Scopus and Google Scholar databases from 2015 to 2025.Results. A small number of studies were included in the meta-analysis. Mean values of systolic and diastolic BP depending on the measurement method used were presented in two studies, which implies high inconsistency in the presented studies and determines the need for a balanced interpretation of the pooled estimate of the difference in mean values for these studies.Absolute values determining the incidence of AF are indicated in four studies.Conclusion. Our systematic review and meta-analysis showed PPG effectiveness for arrhythmia and controlling systolic and diastolic BP at the outpatient stage.
