Atrial Fibrillation Symptoms Quiz
For adults noticing repeated uneven heartbeat episodes, recording when they happen, how long they last, and any tiredness, dizziness, or shortness of breath can help a healthcare professional assess the pattern. ECG-based assessment is needed to determine whether atrial fibrillation is present. For background, read Atrial fibrillation: symptoms, causes and testing.

Frequently Asked Questions
Common questions about this quiz, what it covers, and what your results mean.
These questions have not been clinically validated. Symptoms or watch alerts cannot confirm atrial fibrillation. Call 911 for chest pain, severe breathlessness, fainting or stroke signs happening now or recently without emergency assessment, even if they eased.
Atrial fibrillation, often called AF, is a type of irregular heart rhythm. It can cause symptoms, but some people do not notice any. ECG-based assessment is needed to determine whether it is present.
The feeling of an uneven heartbeat cannot identify the rhythm by itself. An ECG records the heart's electrical activity and is used in assessing possible AF. Describe recurring episodes even if they are not happening during the visit.
Yes. AF can occur without noticeable symptoms. Feeling well or having few symptoms does not rule it out; a clinician considers the medical history and ECG-based findings.
Palpitations describe the sensation of noticing your heartbeat, such as fluttering or pounding. AF is a specific heart rhythm condition. Palpitations alone do not show that AF is present.
AF can cause palpitations, tiredness, dizziness, and shortness of breath, or no symptoms. These symptoms can also have other causes. Note whether they occur together and whether uneven heartbeat episodes return.
ECG-based assessment is needed. Tell the clinician when episodes happen, how long they last, and whether you feel normal between them. Ask how heart rhythm can be assessed when an episode is not happening during the appointment.
No. A watch alert does not confirm AF. Save the alert if available and discuss it with a healthcare professional, who can decide on ECG-based assessment. Emergency symptoms need immediate care rather than waiting to review an alert.
An ECG records the heart’s electrical activity. If episodes come and go, a clinician may arrange longer rhythm monitoring and choose other tests according to the history and examination. Symptoms or a watch alert alone cannot confirm atrial fibrillation.
Yes, dizziness and tiredness can occur with AF, but they are not specific to it. Recording whether they occur alongside uneven heartbeat episodes can help a clinical discussion. Call 911 if you are fainting.
An episode that stops is still worth describing. Write down its approximate start time, duration, and any symptoms that occurred with it. Ask about ECG-based assessment rather than assuming the rhythm is normal because the sensation stopped.
No. Symptom intensity cannot determine stroke risk. If AF has been diagnosed, discuss risk assessment with your clinician and follow your existing care plan, even when symptoms are mild or absent.
Call 911 for current chest pain, severe breathlessness, fainting, or current or recent stroke symptoms such as sudden face drooping, one-sided weakness, or trouble speaking. Call even if stroke symptoms have stopped. Do not drive yourself or delay emergency assessment to arrange an ECG or order blood testing.
