The heightening of PT with using active fixation electrode was higher than passive fixation electrode in acute period(VPT from 0.55±0.10 to 1.00±0.12,P=0.05),but in chronic period the change regularity of both electrodes had not statistics differences.
6.急性期心室螺旋电极PT升高较翼状电极明显(从0.55±0.10uJ升至1.00±0.12uJ,P=0.015),慢性期两种电极PT变化无统计学差异。
