Research On Electrophysiological Process Of Heart In Three-Dimensional Space

1. IntroductionThe heart is one of the most important parts of human's body. It is the pump of the circle of blood. The heart contains four parts, such as left ventricle, right ventricle, left atrium and right atrium. Only all parts work well together, the pump can supply blood to everywhere of body. The working of the heart is an important sign of human's health.The illnesses about heart have become a killer of human. In the developed country, there are many people lose their lives just because this kind of illness every year. In our country, with the developing standard of living, there are more and more people get this kind of illness every year. So we must do something to teach people to prevent this kind of illness, and to do more research about the human's heart, especially the electrical information of the heart. It is more urgent than before to work out something to help the medicinal students to learn the advanced technology about the heart. Because we have not enough doctors who can apply the advanced technology in our country.The electrical information of the heart has some characters, such as frequency, swing, and so on. With the developing standard of research about the heart, the Electrocardiograph (ECG) can not provide enough information. But the Vectorcardiogram (VCG) contains the information of solid, space, and so on, so it can provide more information than ECG.2. Research contentIn the state of many data about ECG have been recorded, we aim at the characteristics of the new technology and work out an equipment which can help medicinal teachers and students to teach and learn the new theory of heart. The equipment bases on the data of ECG and the information of heart in the three-dimensional space, with the account on the computer and the cooperation of the electronic control system, the stimulant heart can work as human's heart to send out electrical information, especially as some ill heart. With the system of collection, the experimenter can get the electronic information under the newtheory of heart. Through the agreement of data which defined by myself, the data can be transmitted to the computer. The application software on the computer can draw a chart based on the data of stimulant heart in the three-dimensional space. Get VCG from ECG.In this part, we talk something about the characteristic of electrical information of the heart firstly, and then the ECG and VCG. In order to using the data of ECG, we talk most about the relation of ECG and VCG. There are detailed introduction about the arithmetic which can identify the characteristic of the QRS circle by computer in this part. And finally, we get the method about getting VCG from ECG.The hardware and software about stimulant heartIn this part, we talk something about how to make the stimulant heart firstly, and then we put our emphases on the design of the electronic control system. The stimulant heart controlled by this system how to work. And in the finally, we introduce something about the method of drawing the PCB. The application softwareIn this part, we talk something about the whole function of the application software firstly, and then we talk something about the technology of OpenGL. Finally, we draw the flow chart of the application software.3. ConclusionThe part finishes the design of the whole equipment, and provides a part of original data about the equipment.
