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.
