What're the symptoms of heart block?

The main symptom associated with heart block is fainting (syncope). The extent to which this occurs depends on the type and extent of the conducting disturbance.

First degree heart block is fairly common. It can sometimes be found in teenagers, young adults and in well-trained athletes. The condition may be caused by rheumatic fever, some types of heart disease and by some drugs. First-degree heart block causes no symptoms. Second degree heart block may not cause symptoms. Second degree block can sometimes progress to third-degree. Third degree heart block is a serious condition that usually affects the heart's ability to pump blood effectively.
