Bradycardia is a slower than normal heart rate. The heart usually beats between 60 and 100 times a minute in an adult at rest. If you have bradycardia (brad-e-KAHR-de-uh), your heart beats fewer than 60 times minute.
Bradycardia can be a serious problem if the heart doesn't pump enough oxygen-rich blood to the body. For some people, however, bradycardia doesn't cause symptoms or complications.
An implanted pacemaker and other treatments may correct bradycardia and help your heart maintain an appropriate rate.
