The heart tissue is rich in blood, which flow is a thermal diffusion process; it can lead to lesion shape differences. The temperature distribution is very hard to obtain through the antenna specific absorption rate, thus affect curative effect. Based on the Pennes bioheat transfer equation, high flow rate of blood effect on microwave ablation in atrial fibrillation was analyzed. Lesion depths and diameters were analyzed.
