4. Symptoms of a Bundle Branch Block

In people who are otherwise healthy, a bundle branch block might be present for years and the doctor usually discovers the condition when diagnosing another issue, such as after a heart attack or when evaluating heart disease. Although not common, people with bundle branch blocks may faint or feel lightheaded. Even though a bundle branch block does not present with many symptoms, it's still important to take it seriously. It could be a sign that part of the heart is not getting the oxygen it needs. Some people with a bundle branch block are also at greater risk for heart disease.
