| Objective | The aim of this study was to determine the effect of long-term right ventricular pacing on left ventricular (LV) mechanical dyssynchrony in children and young adults with congenital and acquired heart block. |
| p Value | 0.011 |
| Conclusion | Compared to group III controls, patients in groups I and II had significantly greater indexed LV endsystolic volumes, lower LV ejection fractions, and increased SDI values. |
