Consequently, it is easier to get fat due to lack of exercise , working pressure , smoking , unhealthy diet habit and so on. However, fatness is one of the main reasons to cause the diseases of cardiovascular system. How do we prevent from the disease of cardiovascular ? The most important thing that we have to do first is to understand and find out what will cause the disease of cardiovascular. The cardiovascular disease is involved in the heart and blood vessel. These diseases are all related to the Arteriosclerosis. According to the statistics of The department of health (DOH), we can figure out that the diseases of cardiovascular always ranks high among the top ten causes of death ; moreover, there are more and more young people to get the problems of cardiovascular. Consequently, it is a very important issue of the prevention and treatment of cardiovascular diseases at present. In order to decrease the possibility of the cardiovascular diseases, we have to comprehend whether the artery is hardening or not. pulse wave velocity is the most important parameter which is used in evaluating the level of arteriosclerosis. Generally speaking, if the blood vessel is harder and the elasticity is worse, then the pulse wave velocity will be faster. In my thesis, I experimented on a mouse and surveyed the photoplethysmography from the palm and thenar of the mouse, and then I could calculate the pulse wave velocity and heart rate of the mouse for testing some treatment and reduce the possibility of arteriosclerosis. The research will be greatly helpful to who may investigate the artery and the other symptoms to these diseases. In addition, I programmed by Visual Basic 6.0 to collect and save photoplethysmography from the mouse’s palm and thenar and then read the data via the program by MATLAB 7.1. Finally, we can analyze the heart rate and pulse wave velocity of the mouse.
