Evaluation of Oxa for Cardiac Activity and Autonomous Nervous System Monitoring
This paper demonstrates the reliability and robustness of Oxa in collecting ECG signals and monitoring heart rate and its variability compared to a medical gold standard ECG monitoring system (AMEDTEC ECGpro systems).
- Oxa and 2 of the most widely used smartwatch models were tested versus medical grade ECG. Smartwatches 1 and 2 had mean differences of up to 14 and 8 BPM at various resting scenarios, standard deviations to their individual averages of 19 and 7 with minor activity and were in many cases deviating by over 20BPM, while Oxa never deviated by more than 1BPM from the medical system.
