Epikardiyal Kalp Pili Takılmış Klinik Olarak Normal Bir Çocukta Holter Monitörizasyonun Önemi

Arrhythmias in congenital heart diseases may be seen due to structural disorders or they may develop as a result of surgical interventions due to repair. The incidence of complete atrioventricular block after cardiac surgery for congenital heart disease was reported to be between 1-3%. Permanent pacemaker implantation may be required in some rhythm problems after open heart surgery. Here, we present a five-year-old boy who has been followed up regular intervals for three years in our outpatient clinic. When he was four-month-old, he had been undertaken congenital heart surgery in another centre and then permanent epicardial pacemaker implantation had been done due to development of complete atrioventricular block. Despite very little or no problems were seen in electrocardiographic evaluations, we determined serious rhythm problems (failure to capture, oversensing and also long pauses up to 5.5 seconds) via holter ECG monitoring performed with regular intervals. In the event of any significant change of setting or battery/lead change in the devices of patients with permanent pacemaker implantation, careful examination of the holter ECG monitoring is essential to avoid unexpected conditions.
