Polar Extra application uses the POLAR H10 heart rate monitor to detect suspicious episodes of Atrial Fibrillation. Atrial fibrillation is a heart condition that causes an irregular and often abnormally fast heart rate. The POLAR H10 bluetooth connection allows you to record in real time on your Android device, the electrocardiogram (ECG) as well as your heart rate. The ECG signal is processed using a convolutional neural network to distinguish between normal beats and Atrial Fibrillation. The neural network makes it possible to detect the RR intervals (time interval between two beats) in the signal and it performs the morphological analysis of the ECG. This analysis allows thanks to the use of a large public database (Physionet.org) to detect suspicious phases of Atrial Fibrillation. It should be noted that the model was validated using a part of the Physionet database completely independent from the part used to build the neural network. The detection is done in real time in the application as well as heart rate monitoring.
The user gives a time interval which defines the frequency of the ECG signal processing and POLAR H10 Extra will give periodically voice indications on the presence of suspected Atrial Fibrillation as well as the average, maximum and instantaneous heart rate. It is possible to perform an analysis of the ECG signal from the beginning at any time. There is no time limit in using the application which can run for hours in the background allowing continuous monitoring of your heartbeats. It is also possible to analyze ECG signals already stored on your device. These are saved in real time in the Documents folder of the Android device. Additional analysis of segment and intervals on the ECG using the Neurokit2 software has been integrated to the application. When launching the application for the first time, please indicate the ID of the Polar H10 device (written on the edge of the sensor) then restart the application.
