Can a smart watch detect atrial fibrillation?
Background: Atrial fibrillation (AF) is the most prevalent arrhythmia and a significant risk factor for stroke and heart disease, making early diagnosis crucial for prevention. Although several smartwatches can detect AF, their accuracy varies, and there is limited information regarding their effectiveness. Using a flashing green light on the underneath side of the smart watch, PPG reflects light to the red blood vessels under your skin and records changes in your blood volume. The sensors in these wearables can also measure how the blood pulsates and identify irregularities or palpitations that indicate AFib.
Can smart watches check ECG?
The ECG app uses sensors on your compatible smartwatch to record the electrical signals that control how your heart beats. This recording is known as an electrocardiogram, or ECG.

Do cardiologists recommend smart watches?
MedStar Health cardiologists and primary care providers see data from these devices every day. Their perspective is clear: smartwatches are a valuable tool for promoting activity and heart-health awareness. But they should be used in addition to, not a replacement for, a medical evaluation. Battery drain, connectivity problems, and delayed notifications are among the most frequently reported user concerns. Keeping the smartwatch clean, updated, and properly configured enhances long-term performance and accuracy. Specific hardware or persistent issues should be addressed through official support channels.Physicians who wore a smartwatch and had access to their personal health data — including information on their heart rate, sleep, breathing patterns and physical activity — reported greater resilience and 54% saw a reduction in the overall odds of burnout compared to those who did not receive a study smartwatch, .
