Abstract
Background and aims Heart rhythm disorders in neonatal period vary from benign to life threatening. Supraventricular tachycardia is the most common symptomatic arrhythmia. The aim of the study was to analyze all cases of supraventricular tachycardia in neonates in our hospital during years 2007-2014 with the follow up period up to the April, 2015. Specialized pediatric cardiac care in our country is provided only in Children’s University Hospital.
Methods We analyzed case histories, ECGs, holter recordings and outpatient follow up records of all the patients with neonatal supraventricular tachycardia during years 2007-2014 selected from hospital`s data base.
Results There were 18 neonates: 13 cases of supraventricular paroxysmal tachycardia (SVPT), 3 cases atrial flutter, 2 cases atrial ectopic tachycardia (AET).4 of them(22%) had antenatal transplacentar treatment with digoxin. The initial treatment of paroxysms was ATF 44%, electrocardioversion 22%, amiodarone infusion 39%. 2 patients were lost to follow up, 14 patients received long time treatment months 6.9±3.3months (digoxin 27,8%, propranolol 38,9%, 3rd class antiarrythmics 11,1%, combined treatment 16,7%) . Only 2 patients experienced heart rhythm disorders beyond neonatal period: 1 case of AET and 1 WPW (prolonged antiarrhythmic treatment).
Conclusions In our study period supraventricular tachycardia in neonates in our hospital was observed in 1-4 cases per year. These patients were in need of timely recognition of the problem and intensive treatment during neonatal period and long time antiarrytmic treatment during first months of life. In most cases (88%) significant heart rhythm disorders were not observed in further life.
