Abstract:
Objective To explore the characteristics of electrocardiographic (ECG) changes after transcatheter closure of ventricular septal defect (VSD). Methods Changes in ECGs of 215 patients after transcatheter closure of VSD from 2002 to 2004 were studied. Results The ECGs of all 215 patients were normal before operation while after operation, ECGs remained normal in 137 patients but 78 patients turned out to be abnormal. Transient atrioventricular interference dissociation occurred in 17 patients and their ECGs recovered to normal after 5 days. Left anterior bundle branch block occurred in another 17 patients and 15 of them returned to normal state 6 days after the procedure. Either right bundle block or left one occurred in 22 patients and their ECGs remained abnormal until they were discharged from the hospital. Advanced or Ⅲ? atrioventricular block occurred in 11 patients, 9 of them returned to normal state, but 2 patients required pocemaker implantation. Conclusion Transcatheter closure of VSD interferes the cardiac conducting system. Most patients can restore normal state, but few may leave behind sequelce.
