How common is palpitations in atrial fibrillation?

During atrial fibrillation, the upper chambers of the heart beat in an uncoordinated way. This can make the pulse feel uneven and may reduce how efficiently the heart fills between beats. Breathlessness, tiredness, reduced stamina, dizziness or chest discomfort may occur alongside palpitations.

A pulse check cannot establish the cause by itself. An electrocardiogram records the heart rhythm, and a clinician may arrange further monitoring if an episode is intermittent. Evaluation also considers conditions and medicines that can trigger or worsen an irregular rhythm.

If palpitations are new or recurring, arrange a clinical review and record the start time, duration, pattern and associated symptoms. Take prescribed medicines as directed and do not alter heart or blood-thinning treatment without medical advice. Ask whether you need rhythm monitoring and an individual plan for stroke prevention.

Call emergency services for palpitations with chest pain, severe breathlessness, fainting, sudden weakness, facial drooping, trouble speaking or a new severe headache. These symptoms may signal a serious heart or circulation problem. Urgent assessment is also sensible when a sustained rapid or irregular heartbeat feels markedly different from your usual pattern.

Ask how atrial fibrillation will be confirmed, whether you need an electrocardiogram or monitor, which symptoms require emergency help, and how your treatment protects both rhythm and circulation.
