Cardiology refers to the branch of medicine that deals with heart and blood vessels disorders. Cardiologists are heart doctors. A sub-specialty of cardiology is electrophysiology, which requires additional training in addition to a general training in cardiology. An electrophysiologist is a specialist in the electrical conduction system of the heart.
