Cardiology is the treatment of diseases of the heart and blood vessels. A cardiologist is a physician who specializes in treating heart conditions such as abnormal heart rhythms, heart attacks, coronary artery disease, congenital heart defects, and disease of the heart valves. A cardiologist can inform your doctor about new drugs or tests that may be beneficial to you.

Some heart conditions can cause permanent damage to the heart muscle, and can be fatal. Methods that cardiologists use to study heart conditions include stress tests, a monitor to record your heart rate and rhythm, a biopsy, which studies a tiny piece of heart tissue, and an echocardiogram, which uses sound waves to show a picture of how your heart works.
