Deep Learning Applications

When using the above applications with the Polar H10 heart rate monitor, please make sure that the battery level of your Polar device is at least 50%.  Normally the application will work for hours in the background, but in some devices, in order to save battery life, Android can drop the bluetooth connection or the application can get killed if it is used for a long time. To avoid this it may be necessary to change some settings on your Android device. Typically, go to Settings/Apps, find the application (Polar H10 ECG Check or Polar H10 Fibrillation) and click on it. Then click on Battery and choose Unrestricted. Also you can go to Settings/Battery, then Background usage limits, Never auto sleeping apps and add yourapplication.

It is best to moisten slightly the belt in order to improve signal quality. A bad signal quality can lead to false positive and thus wrong predictions.

When wearing the Polar H10 belt, make sure you do not have the sensor with the POLAR inscription facing down. In fact, in this case, the recorded ECG will be inverted, which will distort the analysis carried out by the Polar ECG Check and Polar Fibrillation Search applications.
