Your Smartwatch Flagged AFib. Now What?

What to do when a device says your rhythm is off.

If your smartwatch or home blood pressure machine warns of an irregular rhythm, do not panic, but do not ignore it. Write down when it happened, then call a heart doctor to have it checked. FCCI says an irregular heartbeat on your pulse or blood pressure machine is a reason to be suspicious of AFib.

A device is a clue, not a diagnosis

Watches and home cuffs can be very useful. They catch things people would otherwise miss, especially since some people with AFib feel no symptoms at all. But a device alert is a starting point. A doctor still needs to confirm the rhythm with medical testing, such as an EKG, and decide what it means for you.

First, rule out an emergency

Call 911 right away if the alert comes with:

  • Chest pain or pressure
  • Fainting or nearly fainting
  • Severe shortness of breath
  • Face drooping, arm weakness or slurred speech

If you feel fine, the next step is a call to your doctor's office during business hours.

What to write down

  • The date and time of each alert
  • What you were doing, such as resting, exercising or sleeping
  • How you felt: fluttering, racing, tired, short of breath, or nothing
  • Any heart rate numbers the device showed
  • Caffeine, alcohol or new medicines that day

Many watches can save a rhythm strip you can show the doctor. Bring the device or screenshots to your visit.

What happens at the visit

Your doctor will ask about your history and symptoms, examine you, and likely order rhythm testing. FCCI's testing team works with EKGs, Holter monitors and event recorders, which give a fuller, medical-grade picture. If AFib is confirmed, you will talk about stroke risk, rhythm control and next steps.

Do not adjust medicines on your own

If you already take heart medicines or a blood thinner, keep taking them as prescribed unless your doctor says otherwise. Do not start, stop or change anything based on a watch reading alone.

Who to see

A general cardiologist or an electrophysiologist can evaluate a device alert. FCCI has both, including heart rhythm specialists Dr. Firas El Sabbagh and Dr. Deepak Kumar Pasupula.

False alarms happen

Devices can be fooled by movement, a loose band, cold hands or other rhythms. That is why a medical test matters. If the doctor finds no AFib, that is good news, and you can ask what to do if the alerts continue. If AFib is found, catching it early gives you more time to plan stroke prevention and treatment with your doctor.

Keep the device useful

Wear the watch snugly, keep the software updated, and learn how to save or export readings so you can share them at visits.

Do not let a watch replace regular checkups. It is a helper, not a doctor.

Getting care at FCCI

Bring your watch alerts to any FCCI office, from the Southside on AC Skinner Parkway to Westside, Northside, Mandarin/Fruit Cove, Orange Park, Palatka and Waycross. The front desk can confirm your insurance before you come in.

A watch alert is a clue, not a diagnosis. Your doctor will confirm what is going on with real medical testing.
