1·Objective To explore the clinical feasibility of right ventricular inflow tract posterior septal endocardium pacing , in order to find another pacing site for tined electrode.
目的探讨右室流入道靠后间隔心内膜起搏的临床可行性，为翼状电极寻找另一理想起搏部位。
2·The endocardium is smooth, beneath which can be seen a red - brown myocardium .
光滑的心内膜下面是红棕色的心肌。
3·The endocardium is smooth, beneath which can be seen a red-brown myocardium.
光滑的心内膜下面是红棕色的心肌。
4·Results The nuclear of ischemic myocardium was enlargement and abnormity under endocardium. The number of abnormal nucleus in ischemic myocardium was more than that in the normal controls(P
结果心内膜下缺血心肌细胞核异常肥大、畸形，肥大畸形细胞核数目明显多于正常对照组，两者有明显差异（P <0 .0 1）。
