How Is Heart Block Treated?

Treatment depends on the type of heart block you have. First-degree heart block usually needs no treatment.

If you have second-degree heart block, you may need a pacemaker. A pacemaker is a small device that's placed under the skin of your chest or abdomen. This device uses electrical pulses to stimulate the heart to beat at a normal rate.

If you have third-degree heart block, you will need a pacemaker. In an emergency, a temporary pacemaker may be used until you can get a permanent one. Most people who have third-degree heart block need pacemakers for the rest of their lives.

Some people with third-degree congenital heart block don't need a pacemaker for many years. Others may need a pacemaker at a young age or during infancy.

In some cases, acquired heart block may go away if the factor causing it is treated or resolved. For example, heart block that occurs after a heart attack or surgery may go away.

Also, if a medicine is causing heart block, the condition may go away if the medicine is stopped or the dosage is lowered. However, you shouldn't change the way you take your medicines unless your doctor tells you to.
