Which medication type is typically used to control heart rate and treat hypertension?

• A. Diuretics
• B. Beta blockers
• C. ACE inhibitors
• D. Calcium channel blockers

Answer: (B)

Beta blockers are a class of medications that are primarily used to manage heart rate and treat hypertension. They work by blocking the effects of epinephrine (adrenaline) on the beta-adrenergic receptors in the heart. This action decreases heart rate and the force of contraction, which ultimately lowers blood pressure. Additionally, beta blockers help reduce the workload on the heart and improve its efficiency. They are commonly prescribed for various cardiovascular conditions, including hypertension, heart rhythm disorders, and heart failure. While diuretics help eliminate excess fluid and reduce blood pressure, they do not primarily focus on heart rate control. ACE inhibitors are effective in relaxing blood vessels and reducing blood pressure but do not directly impact heart rate. Calcium channel blockers also manage hypertension and can affect heart rate, but their primary mechanism is to relax blood vessels and decrease the heart's contractility. Therefore, beta blockers specifically target heart rate control, making them the appropriate choice in this context.
