Abstract: Objective: The objective of this study was to determine risks, onset and treatment for early postoperative arrhythmias among patients who underwent pediatric cardiac surgery. The primary focus of the study was to gauge results by uniform therapies along with analysis of issues faced by children who were operated at an earlier and later age. Patients & Methods: This prospective study was carried out on a total of 224 consecutive pediatric patients who underwent cardiac surgery at Jinnah Hospital, Lahore (February 2019 to January 2020). In the course of study, a total of 24 patients were excluded as they were treated without cardiopulmonary bypass. Results: Median age of the study population was 24 months (50.1±62.4). The age range for the selected sample was (0.5 to 216 months). Arrhythmia developed among 15 patients (7.5%); most repeated arrhythmia was junctional ectopic tachycardia observed among 7 patients (46.6%) and supraventricular tachycardia observed among 5 patients (33.3%). The occurrence of all junctional ectopic tachycardias happened in the first 24 hours of ICU admission. Five patients responded to conventional management protocols out of seven; whereas, two still required amiodarone infusion. Non-arrhythmias patients required less cardiopulmonary bypass time; whereas, arrhythmias patients required significantly longer duration. Conclusion: Children presented very low arrhythmias onset after open-heart surgery for junctional ectopic tachycardia. There was no significant predictor than a significant longer duration for cardiopulmonary bypass. Multiple factors attribute to arrhythmias following pediatric cardiac surgery and more research work on large scale samples is required to unfold more about the matter.
