[IEEE 2018 IEEE 20th International Conference on e-Health Networking, Applications and Services (Healthcom) - Ostrava, Czech Republic (2018.9.17-2018.9.20)] 2018 IEEE 20th International Conference on e-Health Networking, Applications and Services (Healthcom) - Examination and Optimization of the Fetal Heart Rate Monitor : Evaluation of the effect influencing the measuring system of the Fetal Heart Rate Monitor
摘要： Long-term monitoring of the fetal heart rate (fHR) is important to control the fetal well-being. One of the promising methods for fetal monitoring is fetal phonocardiography which is based on recording fetal heart sounds. This paper presents a compact low-cost device for multi lead fHR measurement. The device introduced allows monitoring of fHR non-invasively and with no side effects for the mother or the foetus. In this case, the device presented is used to measure HR of the adult to compare the performance of various stethoscope heads. In addition to this measurement, the LabVIEW application for signal processing and analysis was improved.

[IEEE 2018 24th International Conference on Pattern Recognition (ICPR) - Beijing, China (2018.8.20-2018.8.24)] 2018 24th International Conference on Pattern Recognition (ICPR) - Variational Mode Decomposition-Based Heart Rate Estimation Using Wrist-Type Photoplethysmography During Physical Exercise
摘要： Heart rate (HR) monitoring based on Photoplethysmography (PPG) has drawn increasing attention in modern wearable devices due to its simple hardware implementation and low cost. In this work, we propose a variational mode decomposition (VMD)-based HR estimation method using wrist-type PPG signals during physical exercise. To remove motion artifacts (MA), VMD was first used and then a post-processing method after VMD was proposed to guarantee the robustness of MA removal. The performance of our proposed method was evaluated on two PPG datasets used in 2015 IEEE Signal Processing Cup. The method achieved the average absolute error of 1.45 beat per minute (BPM) on the 12 training sets and 3.19 BPM on the 10 testing sets, confirmed by the experimental results.
