What is Cardiology?

Cardiology is the specialty within medicine that looks at the heart and blood vessels.  Your heart consists of 4 chambers, which are responsible for pumping blood to your lungs and then the rest of your body. The study of the heart includes the heart muscle (the myocardium), the valves within the heart between the chambers, the blood vessels that supply blood (and hence oxygen and nutrients) to the heart muscle, and the electrical system of the heart which is what controls the heart rate.
