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