Abstract:
Objective To explore if any rules in electrocardiogram changes after transcatheter closure of perimembranous ventricular septal defects ( PMVSD ) . Methods We included all the 358 patients who have accepted transcatheter closure of PMVSD in our hospital between July 2006 to October 2014 and the electrocardiogram (ECG) done in hospital and during follow up in 1,3, 6 and 12 months after operation were all reviewed. Results No changes were found in heart rates and electrical axis during follow-up as compared to preclosure ECG. PR interval was shorter, the QRS duration and QT interval were longer than preclosure. Incidence rate of arrhythmia was 38. 0% ( 136/358 ) and incidence rate of serious arrhythmias ( including Ⅱ° or Ⅲ° atrioventricular block and complete left bundle branch block) was 5. 0%(18/358). Among the 180 patients who had ECG done in all follow up between the first 12 months post closure, the rates of new developed arrhythmias was 12. 8% ( 23/180 ) and severe arrhythmia was 0. 6%(1/180) during follow-up. Conclusions Incidence rate of serious arrhythmias after transcatheter closure of PMVSD is low and most patients have good clinical outcome.
