Final answer:
For a patient with stable atrial fibrillation and controlled ventricular response, treatment usually includes rate control with beta blockers or calcium channel blockers, possible rhythm control with antiarrhythmic drugs, anticoagulation therapy to reduce stroke risk, and in some cases, cardioversion to restore normal sinus rhythm.
Step-by-step explanation:
The appropriate treatment for a stable patient with atrial fibrillation and a controlled ventricular response generally includes several strategies. First, rate control is essential and is usually achieved with beta blockers or calcium channel blockers, which slow the heart rate. In some cases, rhythm control with antiarrhythmic drugs may be necessary, but these can have significant side effects. Anticoagulation therapy with warfarin or direct oral anticoagulants is typically recommended to reduce the risk of stroke. Finally, if the atrial fibrillation is symptomatic or the patient is at risk of heart failure, electrical cardioversion can be used to restore normal sinus rhythm.
