Your heart is the body’s powerhouse, and monitoring it periodically can help you avoid any potential health problems. An electrocardiogram (ECG) test records the heart’s electrical activity, and the Apple Watch promises to measure and monitor your heart health right from your wrist. In this post, I will show you how to set up and take an ECG with your Apple Watch.

How to set up the ECG app on iPhone

Users of Apple Watch Series 4, Series 5, Series 6, Series 7, Series 8, and Apple Watch Ultra can measure heart rate and cadence with just the touch of their wrist.

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

Then switch to your Apple Watch to take an EKG.

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

How to take an EKG with your Apple Watch

Taking an EKG on your Apple Watch isn’t as difficult as it sounds. The process is very simple and straightforward. However, before starting the examination, make sure that the watch is correctly positioned on the wrist and that there are no sudden movements during the specified time.

  1. Press the Digital Crown on your Apple Watch and go to the ECG app.
  2. To start reading, simply place your finger on the crown.
    Remember not to depress the Digital Crown; Just put your finger gently.

  3. The 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.

    When the countdown ends, view your results on your Apple Watch.

Interpret ECG test results

Interpreting EKG test results 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 a heart rhythm disorder that can have severe consequences.
  • Bad recording: If a bad recording is detected, it may be due to motion or poor skin contact of the ECG electrodes.

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