Multi-Site Photoplethysmography Applied to Arterial Systemic Network Mapping: nFISIO Platform

The prevention of cardiovascular diseases requires the implementation of non-invasive studies aimed at identifying vulnerable, asymptomatic individuals with subclinical conditions. In this context, this work proposes the generation of a multi-site arterial map using a portable device that employs photoplethysmography and electrocardiography to evaluate arterial pulse wave morphology, along with biomechanical parameters such as arterial pulse transit time (and its propagation velocity), form factor, and rise velocity. This systemic approach contributes to an integrative understanding of vascular dynamics, leading to a more comprehensive approach to associated pathologies.
