[Huawei] Pulse wave arrhythmia analysis on my band/watch does not work in the daytime or analysis records are incomplete

Problem

After the user opens the Huawei Health app, goes to Health > Heart > Pulse wave arrhythmia analysis, touches the icon in the upper right corner and then Automatic measurement, and enables Automatic arrhythmia detection, the wearable device displays detection records as normal during the night-time, but during the daytime it fails to automatically detect arrhythmia or generate detection logs for long periods time, or arrhythmia detection is otherwise irregular/incomplete.

Automatic arrhythmia detection only works when the watch stays still.

Your device has passed the medical certification and has high requirements on the signal. If it determines that you are still, it will automatically detect arrhythmia. If your arm moves slightly, your device will not start detection. Therefore, the bar chart on the device screen may not have any data within some short periods of time, which is normal. This is no cause for concern.
