What causes heart block in relation to bradycardia?

ANSWER

This is one type of bradycardia, when your resting heart beat is less than 60 beats a minute. If you have heart block, a faulty electrical signal inside your body keeps your heart from pumping and squeezing in a rhythm to move oxygen-rich blood.

Some people are born with it. Others get it later in life. The main cause is a heart attack. Other reasons can include:

  • Heart failure, because the heart is not pumping enough blood for your body
  • Myocarditis, or inflammation of the heart muscle
  • Coronary artery disease, or narrowing of the arteries in the heart
  • Rheumatic fever, which is most common in children who didn’t get treated well for strep throat or scarlet fever
