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 fast enough to keep the body healthy. When this occurs, an electrical device called a pacemaker can be used to help the heart beat at a healthy rate. Medicines can also be used to help restore the heart rate. Or, the doctor may substitute a different medicine when the block is the result of a side effect from a certain type of medicine.
Pacemakers use batteries to work. These batteries can last for years, but will need to be replaced at some point. The pacemaker itself may also need replacing after years of use. The side effects of medicines used to treat heart disease vary, depending on the medicine.
Once a pacemaker is implanted, the doctor will monitor the person's heart rate with each office visit. Medicine for existing heart disease may also need to be adjusted from time to time. With the correct treatment, most people are able to continue with their regular activities.
Regular visits to the doctor and repeat ECG testing, sometimes by telephone, helps pick up any changes in the heart's status. Any new or worsening symptoms should be reported to the doctor.
