abstract = "Calcium channel blockers and beta blockers are medicines commonly prescribed for the treatment of hypertension and tachyarrhythmias. Beta blockers prevent stimulation of the beta-adrenergic receptors at the nerve endings of the sympathetic nervous system and therefore reduce systolic pressure, heart rate, and cardiac contractility and output. Calcium channel blockers block voltage-gated calcium channels and inhibit the influx of calcium ions into cardiac and smooth muscle cells. The decrease in intracellular calcium inhibits cardiac contraction, but promotes vasodilatation. Beta blockers are likely overprescribed; they are ineffective antihypertensive agents. Current evidence supports their use in patients with systolic heart failure and for rate control.",
