Atrial Fibrillation: A Common but Risky Rhythm

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.
