ABSTRACT
Objective To discuss the types,pathogenesis and treatment of early cardiac arrhyth-mias in infants after open heart surgery with congenital heart diseases. Methods 992 infants after open heart surgeries were divided into control group and arrhythmia group. Another junctionalectopictachycardia ( JET)group was separated from arrhythmia group. Various preoperative and postoperative data were com-pared. Results 197 infants suffered from cardiac arrhythmia within 3 days right after open heart surger-ies. After exactly the same surgery procedures,JET group was significantly different with control group in aortic cross-clamp time,cardiopulmonary bypass time and stay in CICU(p<0. 05). As for time of ventila-tion,no significant difference was found between the two groups. Conclusion Early diagnosis and treat-ment of cardiac arrhythmia can not only improve the success rate of open heart surgery,but also promote early recovery.
