Wearable devices like the Apple Watch have revolutionized health monitoring. Their ability to detect arrhythmias such as atrial fibrillation (AF) has saved lives. But how reliable are they?
What It Can Detect
- Irregular rhythms consistent with AF
- Abnormally high or low heart rates
- Variations in sinus rhythm
What It Can’t Replace
- Full 12-lead electrocardiogram (ECG)
- Structural evaluation with echocardiography
- Clinical assessment of symptoms
Scientific Evidence
Stanford’s Apple Heart Study (2019) found the watch had 84% specificity for detecting AF but less than 40% sensitivity in asymptomatic users.
Dr. Chango’s Recommendation
Use your smartwatch as a preventive tool, but always consult a cardiologist if symptoms arise. Technology alerts, but diagnosis requires expertise.
Conclusion
Wearables can save lives, but they don’t replace doctors. Use your Apple Watch wisely and consult Dr. Diego Chango if you notice any symptoms.
