In simple terms

Atrial fibrillation increases stroke risk fivefold. Diagnosis and rhythm management have advanced rapidly.

What you need to remember

Stroke prevention — CHA2DS2-VASc score guides anticoagulation.
Rhythm versus rate — Early rhythm control (cardioversion, antiarrhythmics, catheter ablation) increasingly favoured in symptomatic or recent-onset AF.

Palpitations, breathlessness, fatigue, dizziness. Many cases are asymptomatic and discovered incidentally.

Diagnosis

ECG confirms the rhythm. Wearable devices and smartwatches increasingly detect undiagnosed AF.

Stroke prevention

CHA2DS2-VASc score guides anticoagulation. DOACs (apixaban, rivaroxaban) have largely replaced warfarin for most patients.

Rhythm versus rate

Early rhythm control (cardioversion, antiarrhythmics, catheter ablation) increasingly favoured in symptomatic or recent-onset AF.

Untreated sleep apnea, obesity and alcohol excess fuel AF: addressing them reduces recurrence.
