| 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 | <0.001 |
| Conclusion | Overall, 19 of the 27 patients (70%) exhibited LV dyssynchrony. Compared to those without LV dyssynchrony, patients with LV dyssynchrony had lower LV ejection fractions, had shorter RR intervals. |
