Many times heart blocks are not treated at all. Treatment of other heart problems reduces the risk of the block getting worse. In some cases, the block becomes so severe that heart can no longer beat at the proper pace. When this occurs, an electrical device called a pacemaker can be used to help the heart beat at the proper rate. Medications can also be used to help restore the heart rate.
Pacemakers use batteries to work.
These batteries can last for years, but will need to be replaced. The pacemaker itself may need replacing after years of use. The side effects of medicine to treat existing heart disease varies depending on the drug. If a pacemaker is implanted, the doctor will monitor the person's heart rate afterward. Medicine for existing heart disease may also need to be adjusted.
