Abstract:
A distributed simulation method of electric field based on the atrial defibrillation of the heart modeling and finite element solution is proposed in this study. In order to solve the problem that ordinary clinical trials could not measure the actual distribution of the defibril ation electric field in the heart accurately, this method provides a research tool for electrical defibril ation. A complete atrial anatomical structure in the heart model is used in the research, the finite element method is proceeded to solve; Three parameters: defibril ation threshold voltage, the high field strength rate and the defibril ation threshold energy are set to evaluate the effect of defibril ation. The heart electric field distributions of transvenous atrial defibril ation with different electrode locations or sizes are simulated. The simulation results and the reported results match fairly wel , which initial y verify the feasibility of this method.
