The expansion of the downward main wave scope and the leftaxisdeviation proved to have the same cause.
引起主波向下范围扩大与导致电轴左偏的病因基本相同。

No significant differences were found in the heart rate, QRS intervals, Q T intervals, sinus bradycardia, sinus tachycardia and leftaxisdeviation between exposed and control groups ( P >0 05).
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.
