what do beta adrenergic blockers do
Beta-blockers can also block the stimulation of the heart form electrical impulses-they can control irregular heartbeats-thus lowering the activity of the heart and slowing down the heart rate. Hypertension-beta-blockers lower blood pressure by slowing down the heart rate, as well as reducing the force of the heart. Blood still gets to all parts of the body, but at reduced pressure. Glaucoma-pressure within the eyeball is reduced with beta-blocker eye drops.
Heart problems-for a patient with heart problems beta-blockers can reduce the workload for the heart; so that it does not have to work so hard to supply all parts of the body with oxygen-rich blood. For people with angina, heart failure, or after a heart attack, reducing the heart's workload is crucial.
