Apple Watch with ECG: Benefits and Limitations
Introduction
Smartwatches, including the Apple Watch, have revolutionized personal health monitoring. One of their most significant features is the electrocardiogram (ECG) function, which can detect certain heart conditions like atrial fibrillation (AFib). However, while these devices are useful, they have limitations.
How the ECG Feature Works
The Apple Watch ECG function records electrical activity from the heart using sensors on the watch’s back and digital crown. The user places a finger on the crown, and within 30 seconds, the watch generates an ECG tracing.
Advantages of Apple Watch ECG
- Early Detection of Atrial Fibrillation (AFib): The watch can detect irregular heart rhythms, prompting users to seek medical advice early.
- Convenience: ECGs can be recorded anytime, without a visit to a clinic.
- Monitoring Trends: Users can track heart rhythm changes over time and share data with doctors.
Limitations and Risks
- Not a Replacement for Medical ECGs: The Apple Watch records a single-lead ECG, whereas medical ECGs typically use 12 leads, providing a more comprehensive analysis.
- Limited to Certain Conditions: It mainly detects AFib but does not reliably detect heart attacks, other arrhythmias, or structural heart diseases.
- False Positives or Negatives: Results should always be confirmed by a healthcare professional to avoid unnecessary panic or false reassurance.
Key Takeaways
- The Apple Watch ECG is helpful for screening purposes, particularly for AFib.
- It should not replace a professional medical evaluation for serious heart concerns.
- If an abnormal reading occurs, users should consult their cardiologist for further testing.

If you or your loved ones experience any of these symptoms, you should consult a doctor in time. Remember that self-medication can be dangerous, and timely diagnosis will preserve the quality and life expectancy.
The heart is an organ that does not know how to "keep silent" if something goes wrong. Chest pain, shortness of breath, swelling, dizziness, and rhythm disturbances are the symptoms that require our attention. The best prevention of heart disease is careful attention to your health, regular checkups with a doctor, and a healthy lifestyle. Take care of your heart, and it will serve you for many years!
