*Lone atrial fibrillation is atrial fibrillation in the absence of other risk factors for stroke. Aspirin is the only antithrombotic therapy required for patient with lone atrial fibrillation. If a patient with lone atrial fibrillation is asymptomatic and has no tachycardia, then aspirin is all the patient needs. Rate control is unnecessary.
