兒童室間隔缺損封堵術(shù)后早期完全性左束支傳導(dǎo)阻滯心電圖相關(guān)指標(biāo)的變化
[Abstract]:Objective to observe the electrocardiogram (ECG) changes of children with complete left bundle branch block (CLBBB) in children with simple ventricular septum defect (VSD) after interventional occlusion. Methods 21 children with perimembranous VSD occlusion and early postoperative CLBBB were included in the study. Sex, age and occlusive device size were matched at 1:1. 21 children with simple perimembranous VSD without any arrhythmias during the same period were included as control group. The changes of left ventricular voltage, QT interval, heart rate corrected QT interval (QTc), QT dispersion (QTd), dispersion (QTcd), JT dispersion (JTd) and heart rate corrected JT dispersion (JTcd) were compared between the two groups before operation, 1 day after operation, 3 days after operation, 5 days after operation and 30 days after operation. Results the left ventricular voltage and JTcd of the two groups changed with the change of operation time (P 0.05), and the changes of left ventricular voltage and QTd had the interaction effect between time factor and grouping factor (P 0.05). There was significant difference in JTcd between); CLBBB group and control group (P 0.05). There was significant difference in left ventricular voltage between); CLBBB group and control group at 3 d and 5 d after operation (P 0.05). Conclusion there are differences in left ventricular voltage and JTcd in children with VSD with or without CLBBB, and JTcd may be a reference for predicting the occurrence of CLBBB in early postoperative patients.
