How to Use ECG Monitoring Properly (Guided Instructions)

To achieve more accurate health readings, especially ECG results, proper posture and watch usage are essential:

* Wearing Method: For most users, wearing the watch on the left wrist is recommended to allow easier contact with the ECG electrode using the right hand.

* Body Positioning: During measurement, rest both arms on a table, relax your shoulders, and breathe calmly and quietly. Avoid talking or moving during the process.

* Measurement Procedure:

1. Open the ECG measurement function on the watch.

2. Use your right-hand finger to lightly touch the side ECG electrode button (as shown in the user guide).

3. Maintain contact for 30 seconds continuously without interruption.

4. The watch will begin testing automatically once all conditions are met.

* App Integration: The ECG data is analyzed in real-time and stored within the companion mobile app, where users can review waveform reports, heart rate, HRV, and QT intervals.

* Note: Proper wearing, quiet posture, and continuous finger contact are critical to achieving valid ECG readings.
