| 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 | Of the 27 patients, 14 (52%) had LV ejection fractions < 50%. Patients with LV systolic dysfunction, compared to those without, had larger SDI values, shorter RR intervals, and a higher prevalence of dualchamber pacing. |
