A wireless physiological signal acquisition device showed almost identical R-R peak interval signal coverage compared to a reference system, with a mean difference in heart rate of 0.15 ± 4.65 bpm (P=0.133).
A novel compact wearable wireless sensor for ECG/EMG monitoring demonstrated comparable accuracy to a reference system for R-R interval measurement.
Mean Difference: 0.15
p-value: p=0.133
The acquisition of physiological data are essential to efficiently predict and treat cardiac patients before a heart attack occurs and effectively expedite motor recovery after a stroke. This goal can be achieved by using wearable wireless sensor network platforms for real-time healthcare monitoring. In this paper, we present a wireless physiological signal acquisition device and a smartphone-based software platform for real-time data processing and monitor and cloud server access for everyday ECG/EMG signal monitoring. The device is implemented in a compact size (diameter: 30 mm, thickness: 4.5 mm) where the biopotential is measured and wirelessly transmitted to a smartphone or a laptop for real-time monitoring, data recording and analysis. Adaptive digital filtering is applied to eliminate any interference noise that can occur during a regular at-home environment, while minimizing the data process time. The accuracy of ECG and EMG signal coverage is assessed using Bland–Altman analysis by comparing with a reference physiological signal acquisition instrument (RHS2116 Stim/Recording System, Intan). Signal coverage of R-R peak intervals showed almost identical outcome between this proposed work and the RHS2116, showing a mean difference in heart rate of 0.15 ± 4.65 bpm and a Wilcoxon’s p value of 0.133. A 24 h continuous recording session of ECG and EMG is conducted to demonstrate the robustness and stability of the device based on extended time wearability on a daily routine.
Jeong et al. (Fri,) reported a other. Wireless physiological signal acquisition device and smartphone-based software platform vs. Reference physiological signal acquisition instrument (RHS2116 Stim/Recording System, Intan) was evaluated on Signal coverage of R-R peak intervals (mean difference in heart rate) (MD 0.15 bpm, p=0.133). A wireless physiological signal acquisition device showed almost identical R-R peak interval signal coverage compared to a reference system, with a mean difference in heart rate of 0.15 ± 4.65 bpm (P=0.133).
