Table 2 Evolution of left ventricular shortening fraction

From: Mid-term echocardiographic follow up of left ventricular function with permanent right ventricular pacing in pediatric patients with and without structural heart disease

  Last LV SF before PMI LV SF at last follow-up p
Overall 0.41 ± 0.09 0.39 ± 0.11 NS
ICAVB 0.40 ± 0.07 0.37 ± 0.09 NS
CCHD 0.43 ± 0.10 0.39 ± 0.09 NS
ISHD 0.40 ± 0.11 0.41 ± 0.15 NS
  1. CCHD – patients with complex congenital heart disease
  2. ICAVB – patients with isolated congenital complete or advanced AV block
  3. ISHD – patients with isolated structural heart disease
  4. LV SF – left ventricular shortening fraction
  5. NS – not significant
  6. PMI – pacemaker implantation
