Catastrophe characteristics analysis of heart beating based on electrobiology

This paper built a catastrophe model reflecting the heart beating by the combination of electric-physiology, dynamics of blood flow and the catastrophe theory, open out the mechanism and law of the heart beating from root. The catastrophe control system of pathological heart rhythms, design of virtual heart and total artificial heart are studied through the combination of the same time nonlinear dynamics, wavelet examination technique and ultrasonic image. It provides a new way and theory method for quality diagnosis and treatment to the heart attack. To heart minor axis and four cavities section, draw the outline of the outside edge of ventricles by automatic edge detection technique, and disparted in fix reference axes, finally acquire the quantity result of the each region. It established the foundation to the separating of integer movement into region move. With the nature heart layer, divide to unit, set parameters, low rank dynamics model of velocity combines optical flow constraint equation to establish mathematic model of estimating of virtual heart vector. The physics characteristic of the vector adequately reflects out by this model, more accurate than other calculate way. Overcome the weakness of falsity peak value and take a lot of time of traditional DPIV. It acquired the vector result directly through solve the equation, without dispose after as relation method. By using the region motion, the whole beating of the heart transformed. The sensor type and obtain the information method of the artificial heart are introduced. According to different region sensitivity to different parameter of normal man, different parameters were adopted to describe the region movement of artificial heart.
