SUMMARY
Wearable ECG devices demonstrate high accuracy in detecting atrial fibrillation, with ECG chest patches achieving 96.1% sensitivity and 97.5% specificity, while PPG smartwatches show 97.4% sensitivity and 96.6% specificity. The Apple Watch leads wrist wearables at 90% accuracy for heart rate monitoring and 84% accuracy for AF detection in large-scale studies. However, accuracy decreases with increased physical activity, and devices should complement rather than replace professional medical evaluations.

SUMMARY
Studies show wearable ECG accuracy of 90-98% compared to standard 12-lead ECGs, with AFib detection sensitivity ranging 70-90%. Meta-analysis indicates no significant difference between smartwatches and traditional monitoring methods. Clinical studies report automated algorithms achieving 95% sensitivity and 99% specificity for AFib screening. However, accuracy decreases during exercise and for complex arrhythmias beyond AFib, with limitations in detecting conditions like supraventricular tachycardia or heart blocks.

SUMMARY
Wearable ECG devices show promising accuracy with sensitivity and specificity ranging 70-90% for AFib detection. Apple Watch demonstrates 94.8% sensitivity and 95% specificity, while Samsung smartwatches achieve 94-98% accuracy. Other devices like Withings ScanWatch and Fitbit Sense also perform well. Limitations include higher false positive rates and accuracy variations based on skin tone and activity levels. Professional interpretation remains essential for clinical decisions.
