Cardiology is a branch of medicine dealing with disorders of the heart and parts of the circulatory system. Cardiologists help victims of heart disease return to a full and useful life and also counsel patients about the risks and prevention of heart disease. The quiz below is designed to help one review their knowledge of cardiology.
