Your Smartwatch Flagged Atrial Fibrillation, What Now?

Your Smartwatch Flagged Atrial Fibrillation, What Now?

A growing number of Melburnians are being told by their watch that something’s wrong with their heart. It’s one of 2026’s most common reasons people search “heart monitor near me” — and it’s worth understanding what these alerts mean, and what a proper diagnostic test adds.

What is atrial fibrillation, and why does it matter?

Atrial fibrillation (AFib) is the most common heart rhythm disturbance — an irregular, often rapid heartbeat that can cause palpitations, breathlessness, fatigue or dizziness, though sometimes it causes no symptoms at all.

It matters because untreated AFib meaningfully increases the risk of stroke, which is why catching and confirming it early is so valuable.

2026 Update: Wearables are useful — but they’re a starting point, not a diagnosis

What’s new in 2026: Consumer smartwatches with built-in ECG are now widely used, and several are approved by Australia’s Therapeutic Goods Administration (TGA) as medical-grade for single-lead ECG. They’ve become a genuinely useful early-warning tool — many people first learn of a possible arrhythmia from their wrist.

But a watch alert is a prompt to investigate, not a clinical diagnosis. A single-lead consumer recording can miss episodes, misclassify other rhythms, or flag “possible AFib” that needs confirming with medical-grade, multi-lead monitoring over time.

If your device has flagged an irregular rhythm, don’t panic — but do act. Bring the recording to your GP, who can arrange proper diagnostic monitoring.

How we confirm it: Holter and extended monitoring

Because AFib often comes and goes, the key is recording your heart over long enough to catch the event:

  • 12-lead ECG — a quick, non-invasive snapshot of your heart’s electrical activity.
  • Holter monitor — a small device worn for 24–48 hours during normal activity.
  • 28-day HeartBug monitor — extended, long-term wearable monitoring that dramatically improves the odds of capturing infrequent episodes that a short test (or a watch) would miss.

At Prime Cardiology on St Kilda Rd, rhythm monitoring is reported by a specialist cardiologist, Dr Vahid Moosavi — so an ambiguous smartwatch alert becomes a clear answer and, where needed, a plan to protect you from stroke.
