How do beta blocker drugs affect exercise? - 1 views

Beta blockers are a type of cardiac medication prescribed after a heart attack or to treat abnormal heart rhythms (arrhythmias) and other conditions. They slow down your heartbeat, and that raises a common question about them: Do they affect your ability to exercise?

Beta Blocker BasicsBeta blockers relieve stress on your heart by slowing the heartbeat. This decreases the force with which the heart muscle contracts and reduces blood vessel contraction in the heart, brain and throughout the body. They are prescribed under several common brand names, including Propranolol (Inderal), Metoprolol (Lopressor), Atenolol (Tenormin) Acebutolol (Sectral), Bisoprolol (Zebeta) and Nadolol (Corgard).

Beta blockers may be used to treat abnormal heart rhythms and to prevent abnormally fast heart rates called tachycardia, or irregular rhythms like atrial fibrillation. Since they reduce the demand of the heart muscle for oxygen, they may be useful in treating angina, or chest pain, which occurs when the oxygen demand of the heart exceeds the supply. Beta blockers improve survival after a heart attack and also are used to treat high blood pressure and other heart conditions.
