Atenolol is a class of medicine called a beta blocker. Beta blockers decrease the heart rate by blocking the chemicals that normally send impulses to the brain telling your heart to beat faster. As a result, your heart rate (pulse) slows. Atenonol slows your pulse.
Atenolol is a beta-blocker. Beta-blockers are medication used primarily in the treatment of hypertension, heart disease, and other cardiovascular conditions. It may, however, be used to treat conditions outside of the cardiovascular system. One common effect of beta-blockers, like atenolol, is decrease in heart rate, or pulse.
atenolol is used to treat hypertension and angina, but pulse rate is the rate at which your heart beat. This is the relation between atenolol and pulse rate
