A cardiologist is a physician specialising in the treatment of problems of the cardiovascular system-the heart, arteries, and veins.

The cardiologist's field of specialty will include the diagnosis and treatment of congenital heart defects, coronary Heart disease, heart failure, valvular heart disease as well as electrophysiology (the study of the electrical properties of biological cells and tissues).

Cardiologists should NOT be confused with cardiac, cardiothoracic and cardiovascular surgeons who perform cardiac surgery via sternotomy (cutting through and removing the sternum or breast bone to allow access to the heart and great vessels).

The word cardiology comes from the Greek καρδίᾱ, kardiā, "heart"; and -λογία, -logia "knowledge".
