The QRS axis was of no significant difference between RVIS pacing and sinus rhythm. However, there were tendency toward right deviation at RVOT pacing and toward left deviation at RVA pacing.

与正常窦性心律时的额面平均心电轴比较，RVIS起搏时接近正常，RVOT起搏时电轴呈右偏趋势，RVA起搏时呈左偏趋势。

Case 4 represents a right-axis deviation (Figure 6), in which the interventricular septum is almost parallel to the anteroposterior line.

病例4是表示心轴右偏（图6），室间隔与前后线几乎平行。
