Prescribing Safety Assessment (PSA) Practice Exam

What are the most common medications used for controlling heart rate in atrial fibrillation?

1. Beta Blockers - Bisoprolol

2. ACE Inhibitors - Lisinopril

3. Antidepressants - Sertraline

4. Diuretics - Furosemide

The correct answer is: Beta Blockers - Bisoprolol

The most common medications used for controlling heart rate in patients with atrial fibrillation are beta blockers such as Bisoprolol. Beta blockers work by blocking the effects of adrenaline on the heart, which results in a slower heart rate and reduced workload on the heart. They are particularly effective in managing the elevated heart rates that can occur in atrial fibrillation, thus helping to improve symptoms and overall patient stability. In addition to their primary role in rate control, beta blockers also contribute to improved outcomes in patients with atrial fibrillation who may have underlying heart conditions, such as heart failure or coronary artery disease. The use of beta blockers as first-line agents in this context is well established in clinical practice. In contrast, the other medication classes listed do not primarily serve the purpose of controlling heart rate in atrial fibrillation. ACE inhibitors like Lisinopril are used primarily for blood pressure control and heart failure management rather than heart rate control. Antidepressants such as Sertraline are not indicated for heart rate management but may be used in patients with anxiety or depressive symptoms. Diuretics, such as Furosemide, are utilized for fluid management and heart failure but do not have a direct impact on heart rate control in the context of
