Description

Analysis of data about newborn’s supraventricular tachycardia (SVT) in Children’s Clinical University Hospital (CCUH), the type of SVT mechanism, applied treatment, its duration and SVT complications.. This is a retrospective study. Research is comprised of data about newborns hospitalized to CCUH due to SVT from 2015 to 2020. Data was collected from CCUH patient’s clinical histories and was analyzed by descriptive statistics methods. Patients were followed-up for 3 to 8 years.. Out of total of 25 patients 21 (84%) were born in time and 4 (16%) were born premature.  SVT mechanism’s types used were: atrioventricular re-entrant tachycardia (AVRT) for 13 (52%) patients, atrioventricular nodal re-entrant tachycardia (AVNRT) for 4 (16%) patients, ectopic atrial tachycardia (EAT) for 5 (20%) patients and 3 (12%) patients had not differentiated SVT. Emergency treatment was aplied to 2 (18%) with vagal maneuver, adenosine to 13 (52)% and cardioversion to 3 (12%) of total number of patients. Preventive therapy was administered to 24 (96%) of patients, out of them 13 (54%) used propranolol. 14 (56%) of patients received therapy until one year of age. On avarage, therapy was received until 11.6 ± 6.7 months of age. 9 (40.9%) of patients followed the same type of therapy from beginning until termination. SVT complications were observed in 3 (12%) of patients. Anatomical heart defect was diagnosed in 1 (4%) of newborns with SVT. Other congenital anomalies were in 2 (8%) of patients.. The most common SVT mechanism type is AVRT. The most frequent medical treatment was propranolol. Mostly, monotherapy for newborns with SVT is effective. Most patient's heart rhythm disorders disappeared until one year age. Complications are not common in newborns with SVT. A structural anatomical heart defect is a rare cause of SVT in newborns. SVT in newborns is not associated with other congenital anomalies.
