3. How to record an ECG using your OnePlus Watch?




  • Make sure the device is properly worn. Open the app list and choose 'ECG'. If it’s your first time using this feature, specify which wrist the device is on.

  • Rest your arms flat on a table or on your lap. Keep your arms and fingers relaxed.

  • Place your finger on the lower button to start a measurement, which lasts for 30 seconds.

  • During the measurement, remain still, breathe steadily and avoid talking. Keep your finger gently resting on the lower button without pressing it.

  • If the measurement is interrupted, the screen will stop displaying your ECG waveform. You will be prompted to gently place your finger on the electrode and may also be shown other measurement tips.

  • After 30 seconds, the measurement will end and the results will pop up. On this screen, you can add any symptoms you are currently experiencing. You can go to the OHealth app on your phone to view the ECG data in detail.

4. How to review your ECG report on OnePlus devices?




  • The ECG results include: Sinus rhythm, Atrial fibrillation, Very low Heart Rate, Low Heart Rate, High Heart Rate, Very high High Rate, and Inconclusive.

      • Sinus rhythm

A sinus rhythm is a normal heartbeat rhythm where electrical pulses are generated by the sinus node.

    • Atrial fibrillation

Atrial fibrillation is a common cardiac arrhythmia characterized by irregular and often abnormally fast heartbeats.

    • High or low HR

      • Heart rates below 40 bpm are considered very low.

      • Heart rates below 50 bpm are considered low by default.

      • Heart rates above 100 bpm are considered high by default.

      • Heart rates above 150 bpm are considered very high.

    • Inconclusive

The ECG may indicate some heart conditions, but they are not the conditions that the App is designed to identify, so no conclusive result can be obtained from the diagram.

  • 'Weak signals' and 'Poor signals': ECG signals is too low or there is significant interference in the ECG signals, respectively. In either case, you are advised to repeat the ECG test.

  • You could share the report in PDF format in OHealth app.
