beta blockers (-lol)

KNOW: BP, A-RATE
hold meds if HR is <60 or SBP <90 Beta-blockers "block" the effects of adrenaline on your body's beta receptors. This slows the nerve impulses that travel through the heart. As a result, your heart does not have to work as hard because it needs less blood and oxygen. Beta-blockers also block the impulses that can cause an arrhythmia. decreases HR & decreases the force of the heart's contractions & decreases cardiac output resulting in lower demand for oxygen USES: htn, angina, acute MI, CHF and supraventricular tachycardia.
