- Comparisons with medical devicesHUAWEI wearable devices are generally compared against the gold standard (ECG) with an error range of ±10 bpm. If your heart rate is lower than 37 bpm, your wearable device's heart rate monitoring will not be useful. In this case, it is recommended that you use a medical device to check your heart rate.
- Different measurement principles: Wearable devices use optical signals to monitor pulses, and these signals are affected by such factors as external ambient light and slight arm movements, whereas medical devices use an arterial pressure meter (sphygmomanometer) and ECG (gold standard) for measurements. Therefore, the results may differ.
- Different measurement periods: Wearable devices display measurement results in real time, whereas medical devices take an average value per minute. Therefore, the results may differ. You can calculate an average one-minute heart rate value based on the data obtained by your wearable device, and then compare it with that from a medical device.
