How to set up the ECG app on iPhone

Apple Watch Series 4, Series 5, Series 6, Series 7, Series 8, and Apple Watch Ultra users can measure heart rate and rhythm by simply touching their wrist.

1. Please make sure this feature is available in your country or region before starting the procedure.
2. Open the Health app on your iPhone paired with your Apple Watch.
3. Tap the Overview tab, then tap Heart → Electrocardiograms (ECGs) → tap Set Up ECG App.
4. Then enter your date of birth and click Continue → Read the information on the screen and click Continue.
5. Finally, you are on the Setup Complete screen → click Finish.

Then go to your Apple Watch to take an ECG.

Note. The ECG app is not intended for users under the age of 22.

How to take an ECG with Apple Watch

Taking an ECG on the Apple Watch is not as difficult as it seems. The process is quite simple and straightforward. However, before starting the scan, make sure that the watch is correctly placed on the wrist and that there are no sudden movements during the set time.

1. Press the Digital Crown on your Apple Watch and navigate to the ECG app.
2. To start reading, simply hold your finger on the crown. Remember not to press the Digital Crown; just put your finger gently.
3. Reading will take about 30 seconds. Do not lift your finger until the reading is complete.
4. After the countdown is complete, you can view your results. In my case it is sinus rhythm.

Interpret ECG Test Results

Interpreting the results of an ECG test is very simple. It is important to know what each result means in order to better understand your heart health.

• Sinus rhythm: Sinus rhythm indicates that your heart is beating at a normal rate.
• Inconclusive: An inconclusive result needs further testing as there is no definitive answer.
• Low or high heart rate. A low or high heart rate may indicate a potential heart problem that needs attention.
• Atrial fibrillation: Atrial fibrillation is an irregular heartbeat that can have serious consequences.
• Bad recording: If a bad recording is detected, it may be due to movement or poor skin contact with the ECG electrodes.

Apple Watch won’t give you a detailed report; it will simply summarize your readings. Go to your iPhone for detailed analysis.
