How does an ICD help treat abnormal heart rhythms?

ANSWER

An ICD, or implantable cardioverter defibrillator, is an electronic device that constantly checks your heart rate and rhythm. When it finds a very fast, abnormal heart rhythm, it delivers energy to the heart muscle. This causes the heart to beat in a normal rhythm again.
