Perinatal arrythmia is described as abnormal heart rates or existence of extrasystoles in the fetal or neonatal period. In this study, neonates admitted to the Çukurova University Neonatal Intensive Care Unit between 1 January 1998-30 June 2003 for arrythmia or who were diagnosed as arrythmia after hospitalization were evaluated retrospectively. In this period, 21 of 4465 patients (0.4% of all patients) was diagnosed as arrythmia. Supraventricular tachycardia were determined in 12 (57.1%), ventricular tachycardia in two (9.5%), and ventricular fibrillation in two (9.5%), atrioventricular block in five (23.8%) patients. When infants in the neonatal intensive care units are classfied according to diagnosis, frequency of arrythmia is low. Although arrythmia in the neonatal period is rare, treatment must be urgent.
