Objective: Neonatal arrhythmias (NAs) are defined as abnormal heart rate and rhythm in the neonatal period. Various inheritent cardiovascular, systemic and metabolic abnormalities precipitate NAs. We sought to evaluate incidence, types and implications of NAs.
Methods: A retrospective, observational study was performed on newborns who were diagnosed with NAs during hospitalization in a neonatal intensive care unit (NICU), or who were admitted in four NICUs in North Maharashtra from May 2018 to June 2021.
Results: Forty two neonates with arrhythmias were identified. The incidence of arrhythmias was 0.67% in the four NICUs. Mean gestational age was 36 (29–42) weeks. Eighteen of the infants (42.85%) were diagnosed with fetal arrhythmia (FA) during the third and last trimester of pregnancy. The distribution of NAs types was as follows: Twelve (28.57%) supraventricular tachycardia (SVT), Twelve (28.67%) premature atrial contractions (PACs), Seven (16.67%) premature ventricular contractions (PVCs), three (7.14%) multiple arrhythmias such as SVT + PAC and AV block + PVC, and six babies (14.28%) had AV block. Wolff–Parkinson–White syndrome (WPW) was present in two patient. An association of NAs with congenital heart defects was identified in eighteen cases.
Conclusions: Nonbenign cardiac arrhythmias are important cause of infant morbidity, if undiagnosed and untreated can be fatal. It is important for the pediatrician to be aware of the etiology, development and natural history of arrhythmias in the fetal and neonatal period.
