Wearables for Heart Health Awareness: What the Research Says
Consumer devices provide information, not diagnoses. Home blood pressure monitoring is supported by the 2025 AHA/ACC guideline when a validated device and correct technique are used. Published studies examine single-lead ECG and smartwatch notifications for atrial fibrillation. These devices cannot detect a heart attack. Chest pain, fainting or palpitations need urgent medical care, not an app.

Blood pressure
Check independent validation lists for the specific model and cuff size, and bring readings to your clinician.
Rhythm notifications and ECG
Published studies address detection of atrial fibrillation or arrhythmias. A notification or recording needs confirmation by a clinician.
Heart-rate sensors
Chest-strap sensors have been used as comparison measures in research; wrist-worn devices vary in accuracy.
FAQ
Can a smartwatch detect a heart attack?
No. Seek emergency care for symptoms.
