Yes, the Apple Watch Series 8 does feature an Electrocardiogram (ECG) app, allowing users to take an on-demand ECG similar to a single-lead electrocardiogram.
The inclusion of the ECG feature makes the Apple Watch Series 8 a powerful tool for personal health monitoring, particularly concerning heart health. This functionality allows users to capture heart rhythm data directly from their wrist, which can then be shared with medical professionals.
Understanding the ECG Feature on Apple Watch Series 8
The ECG app on the Apple Watch Series 8 is designed to record the electrical pulses that make your heart beat. By placing your finger on the Digital Crown, the app can then check these signals for signs of Atrial Fibrillation (AFib), a common form of irregular heart rhythm.
Key aspects of the Apple Watch Series 8 ECG:
- Availability: The ECG app is available on Apple Watch Series 4 or later models, which includes the Apple Watch Series 8. It's important to note that the ECG app is not available on Apple Watch SE models.
- Functionality: It captures a single-lead ECG, which can classify heart rhythm as either AFib or sinus rhythm (a normal, regular pattern).
- Irregular Rhythm Notification: Beyond the on-demand ECG app, the Apple Watch Series 8 also offers an irregular rhythm notification feature. This passively monitors your heart rhythm in the background and can alert you to potential signs of AFib.
- Important Note: The irregular rhythm notification feature is not designed for individuals who have already been diagnosed with Atrial Fibrillation. If you have been diagnosed with AFib, you should consult your doctor for appropriate monitoring and management.
- User Experience: Taking an ECG is simple: open the app, rest your arm, and place your finger on the Digital Crown for 30 seconds.
- Data Sharing: All ECG recordings are stored in the Health app on your iPhone, which can be exported as a PDF to share with your doctor.

Benefits and Limitations
While the ECG feature on the Apple Watch Series 8 is a valuable health tool, it's crucial to understand its role.
Benefits:
- Early Detection: Can help detect potential signs of AFib, enabling users to seek medical attention earlier.
- Peace of Mind: Provides users with the ability to check their heart rhythm on demand if they experience symptoms like palpitations or a racing heart.
- Data for Doctors: The recorded ECG data can offer valuable insights for healthcare professionals, aiding in diagnosis and treatment plans.
- Convenience: Offers a portable and accessible way to monitor heart health outside of a clinical setting.
Limitations:
- Not a Diagnostic Tool: The Apple Watch ECG is not intended to replace traditional diagnostic methods or a doctor's visit. It's a screening tool.
- Cannot Detect All Heart Conditions: It cannot detect heart attacks, blood clots, strokes, or other heart-related conditions.
- Accuracy: While generally accurate for its intended purpose, various factors can influence results, and it may not always capture an AFib event if it's intermittent.
- Medical Consultation Still Required: Always consult with a healthcare professional for any health concerns or before making any medical decisions.
How the ECG App Works
The Apple Watch Series 8 uses electrodes built into the Digital Crown and the back crystal. When you activate the ECG app:
- Open the ECG App: Tap the ECG app icon on your Apple Watch.
- Rest Your Arms: Place your arms on a table or in your lap to keep them still.
- Place Finger on Digital Crown: Gently rest the index finger of your opposite hand on the Digital Crown. You don't need to press it.
- Wait 30 Seconds: The app will begin recording. After 30 seconds, your heart rhythm classification will appear.
The result will categorize your rhythm as either Sinus Rhythm (normal), Atrial Fibrillation (AFib), Inconclusive, or Poor Recording.
This functionality empowers users with greater awareness of their heart health, serving as an excellent companion for proactive well-being.
