Abstract

Background: Reliable estimation of heart rate and beat-to-beat intervals is essential for cardiovascular monitoring. Smartphone sensors such as photoplethysmography (PPG) and inertial measurement units (IMUs) offer accessible measurement possibilities, but their reliability depends on acquisition conditions. Methods: In this observational pilot study, simultaneous PPG and accelerometer signals were recorded using smartphones across three acquisition configurations: single-device supine (M1), single-device seated (M2), and synchronized dual-device recordings (M3). RR intervals were derived using identical filtering and peak detection pipelines. Results: Agreement between accelerometer- and PPG-derived RR intervals differed significantly between configurations (Kruskal-Wallis H = 15.98, p
