Junctional ectopic tachycardia is a form of supraventricular tachyarrhythmia which is very common after cardiac surgery. It is more often detected in pediatric age group. The development of JET is because of multiple risk factors and triggers. The etiopathology is complex and diagnosis may be difficult. The association of JET creates hemodynamic alteration, delay extubation, ICU stay and hospital discharge. The treatment of JET is not fully established; many researches continue to explore better understanding and its management. Hence in this review authors described the different aspects epidemiology of JET after cardiac surgery in the recent literatures from different data base. The results from available studies suggest that younger age children, long bypass and cross clamp time, particular set of surgery, hyperthermia, use of inotrope and hypomagnesemia are the risk factor for inducing JET. Management of JET is complex; some occasions resistant to treatments and self-limiting. Hypothermia, judicious use of inotropes, amiodarone, dexmedetomidine, magnesium and radiofrequency ablation are most effective remedies for controlling JET.
