Key result
Amiodarone remains the preferred drug for JET after congenital heart surgery alongside increasing dexmedetomidine use.
Why the study?
Junctional ectopic tachycardia is a common post-congenital heart surgery dysrhythmia associated with increased perioperative morbidity and mortality, requiring effective recognition and management.
This review highlights amiodarone as the primary pharmacological treatment for junctional ectopic tachycardia following congenital heart surgery, with dexmedetomidine emerging as a useful adjunct.
Supports amiodarone preference for post-operative JET; leaves open dexmedetomidine role without prospective trials.
Junctional ectopic tachycardia is a common dysrhythmia after congenital heart surgery that is associated with increased perioperative morbidity and mortality. Risk factors for development of junctional ectopic tachycardia include young age (neonatal and infant age groups); hypomagnesemia; higher-complexity surgical procedure, especially near the atrioventricular node or His bundle; and use of exogenous catecholamines such as dopamine and epinephrine. Critical care nurses play a vital role in early recognition of dysrhythmias after congenital heart surgery, assessment of hemodynamics affecting cardiac output, and monitoring the effects of antiarrhythmic therapy. This article reviews the underlying mechanisms of junctional ectopic tachycardia, incidence and risk factors, and treatment options. Currently, amiodarone is the pharmacological treatment of choice, with dexmedetomidine increasingly used because of its anti-arrhythmic properties and sedative effect.

Catton et al. (2020) conducted a review in Junctional ectopic tachycardia after congenital heart surgery. Amiodarone is the pharmacological treatment of choice for junctional ectopic tachycardia after congenital heart surgery, with dexmedetomidine increasingly used for its anti-arrhythmic properties.
