Analysis of heart rate variability, which is calculated using the R-R intervals (RRI) of electrocardiogram (ECG), provides beneficial information for both clinical and healthcare diagnoses. To achieve the required accuracy for RRI measurement using the wearable telemetery system, two R-wave detection methods (one based on voltage threshold and another that adopts differential peak detection) were...
A telemetry system for the measurement of heart rate variability (HRV) has been developed with a low-cost manufacturing process and a low-power consumption design. All the components and functions for the RRI measurement were implemented on a wearable telemeter which can operate for up to 10 hours with a rechargeable Li-Polymer battery, and the RRI data is stored into a smartphone via a Bluetooth...
