Objectives: The purpose of this study is to review the simulator for cardiovascular system. Methods & Results: Simulators were classified according to the structure and function of cardiovascular system. Heart and blood vessel were selected as the represent of structure. Blood pressure and blood flow were chose as the functional index. With the view points of four keywords, four kinds of simulators were selected: artificial heart, pressure simulator, flow simulator, and pulse simulator.
