Definition

Noun: A beta blocker is a type of medication. It works by blocking the effects of certain natural chemicals (like adrenaline) on the beta receptors of the heart and blood vessels. This action decreases the heart's force and rate of contraction, which lowers blood pressure and reduces the heart's workload.
