Observation of Continuous Blood Pressure with Posture Change Using a Wearable PTT Monitoring System

摘要

Smart healthcare services are continuously is increasing due to rapid industrialization and increasing chronic diseases. Significant research has focused on monitoring the health of an individual health in real time and to prevent disease in advance. This paper implemented a wearable ECG and PPG measurement system to conveniently monitor personal health in daily life. The proposed system used pulse transit time, the time difference between ECG and PPG R-peak signals. To evaluate the proposed system performance, we compared it with an existing commercial system to observe blood pressure and pulse wave changes according to posture, and validated the effectiveness of the proposed system.
