Unconstrained Pulse Transit Time Measurement System for Computer Users

- Summary
- Metrics

Abstract

Pulse Transit Time (PTT) is a simple non-invasive method to evaluate vascular function using photoplethysmography(PPG) and electrocardiography(ECG). This study introduces unconstrained PTT measurement method for computer users and evaluates that. The proposed system consists of chair and mouse those can measure ECG and PPG respectability. PTT was defined as time delay between ECG R peak and PPG steepest point. The correlation coefficient between PTT that measured from this system and conventional PTT was 0.93. This work will provide many opportunities for ubiquitous health monitoring.
