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.
