In this paper , by using a 2d anatomical model of the intact sinoatrial node ( sa ) node and surrounding atrial muscle of the rabbit heart proposed by zhang et al . , The effect of the distribution of death cells on the pacemaking and conductibility of sa node is investigated by computer simulation .

本文利用zhang等人构建的兔子心脏窦房结心房细胞完整的二维解剖模型，通过计算机仿真模拟研究了死亡细胞分布对心脏起搏和传导的影响。
