What are the signs and symptoms of the disease?

Symptoms depend on how severe the heart block is and in what part of the heart it occurs. Often, heart block causes no symptoms. If the heart block is severe enough, the heart rate will slow, and symptoms of low blood pressure or stroke will appear. The person may feel dizzy, weak, confused, or may have less tolerance for exercise. At times, some people may even pass out.
