Do beta blockers produce a negative chronotropic effect?

Yes, beta blockers produce a negative chronotropic effect, meaning they decrease the heart rate. They achieve this by blocking beta-adrenergic receptors, which reduces the effects of adrenaline and noradrenaline on the heart. As a result, beta blockers are often used to manage conditions like hypertension and certain arrhythmias, as well as to reduce heart rate during stress or exercise.
