What are the adverse effects of beta blockers during cardiac rehabilitation?

Beta blockers: Beta blockers are the drug of choice for cardiac patients for prevention of future coronary events. The drug can lower the peak heart rate during exercise. However, patients can continue to get a good training effect even on the beta blockers. The benefits of the drugs far outweigh the potential risks unless the person has severe asthma that could be potentially made worse by the beta blockers.

Beta blockers: Beta blockers prevent sudden arrhythmia after cardiac events such as heart attacks and after heart surgery. These drugs have been found to save lives after cardiac events. The benefits outweigh the risks. However, side effects include fatigue, low blood pressure, dizziness and slow heart rates. There are different beta blockers, all of which have different effects, both good and bad.
