Key result
Endocardial temporary pacemaker implantation in 45 children resulted in successful conversion to sinus rhythm and pacemaker removal in 55.56% overall, and 80.00% in those with fulminant myocarditis.
Why the study?
Endocardial temporary pacemakers are widely used in adults, but application and clinical experience in pediatric cardiovascular cases are relatively limited.
Observational (n=45)
No
Endocardial temporary pacemakers demonstrate high efficacy in pediatric patients with critical heart disease, particularly in those with fulminant myocarditis where 80% recovered sinus rhythm.
Supports temporary endocardial pacing consideration in pediatric fulminant myocarditis; leaves open need for randomized confirmation.
Endocardial temporary pacemakers (TP) are widely used in the treatment of cardiovascular diseases in adults, but their application and clinical experience in the treatment of pediatric cardiovascular cases are relatively limited. This study aims to share the experience of using endocardial TP at a pediatric medical center in China. The study included patients who received their first endocardial TP implantation in the Department of Cardiology at Children's Hospital of Chongqing Medical University, China, from 2016 to 2022. A retrospective analysis of their clinical data was conducted. Our study involved 45 children who underwent endocardial TP implantation. Among these, 25 children (55.56%) converted to sinus rhythm after pacemaker parameter adjustment and the pacemaker was successfully removed; 13 children (28.89%) did not recover sinus rhythm and ultimately required a permanent pacemaker; in 4 cases, the family refused permanent pacemaker implantation; in 1 case, the treatment was abandoned by the family; and 2 children died during hospitalization. Notably, among the 20 children with fulminant myocarditis (FM), 16 children (80.00%) converted to sinus rhythm after pacemaker parameter adjustment and the pacemaker was successfully removed; 3 children (15.00%) ultimately received a permanent pacemaker; and 1 child died during hospitalization. Endocardial TP have shown remarkable efficacy in the treatment of critical heart disease, especially FM.
