Atrial fibrillation and ESC guidance

ESC commonly refers to the European Society of Cardiology. Its guidance helps clinicians structure decisions, but your plan still depends on your symptoms, medical history, examination and test results.

Atrial fibrillation makes the upper chambers of the heart beat irregularly. Assessment commonly includes an electrocardiogram to confirm the rhythm, a review of possible triggers and other heart conditions, and an evaluation of clot and bleeding risks.

Treatment is not based on heart rate alone. Clinicians also consider whether symptoms limit daily life, whether restoring a regular rhythm is appropriate, and whether anticoagulation is needed to reduce stroke risk. These decisions can change as health conditions and medicines change.

Take prescribed medicines consistently and do not stop an anticoagulant or heart-rate medicine without clinical advice. Record episodes of palpitations, breathlessness, dizziness or reduced exercise tolerance, including what you were doing when they began.

Bring an up-to-date medicine list to reviews. Discuss blood pressure, sleep problems, alcohol intake, smoking, weight, physical activity and other conditions that may influence atrial fibrillation. Follow-up allows the care team to reassess symptoms, pulse, treatment effects and clot-prevention needs.

Call emergency services for chest pain, severe breathlessness, fainting, or sudden facial droop, arm weakness, speech difficulty, confusion or loss of balance. These symptoms require urgent assessment even if they settle, because they can signal a heart emergency, stroke or transient ischaemic attack.

Arrange prompt medical advice if palpitations are new, sustained, worsening or accompanied by dizziness. Contact your care team if treatment causes unusual bleeding, black stools, vomiting blood or a significant head injury.

Ask what your electrocardiogram shows, which treatment goal is most relevant now, how your clot and bleeding risks were assessed, what medicine effects need attention, and when the plan should be reviewed. If rhythm treatment is proposed, ask what preparation and follow-up it involves.
