Symptoms of Heart Block
Heart Block can be grouped into first-second-, third-degree heart blocks. The electrical signals that cause the heart to beat are either slowed, partially blocked, or completely blocked. Signs and symptoms depend on how severe the heart block is.
What Causes Heart Block?
Heart block is often caused by problems with the electrical paths of the heart. This may result from the swelling and scarring of heart tissues from previous heart conditions. This may include myocardial ischemia (decreased blood supply to the heart), infections, tumors, or surgery. Certain heart medicines may also cause heart block. Heart block may also be a condition that you are born with.
