Аннотация
BACKGROUND: Junctional ectopic tachycardia (JET) is a well-recognized postoperative arrhythmia in pediatric patients but is rarely described in adults following cardiac surgery.
CASE SUMMARY: A 31-year-old man developed acute dyspnea and palpitations on postoperative day 4 following aortic valve replacement and ascending aorta replacement. Telemetry revealed sustained narrow-complex tachycardia with atrioventricular dissociation, ventricular predominance (V > A), and QRS morphology identical to sinus rhythm. Other causes of postoperative tachycardia were systematically excluded, and JET was diagnosed. Conservative management resulted in spontaneous resolution of the arrhythmia.
DISCUSSION: JET is an uncommon but important cause of postoperative tachycardia in adults. This case emphasizes the diagnostic value of careful electrocardiogram analysis in differentiating JET from other narrow-complex tachycardias and preventing unnecessary interventions.
TAKE-HOME MESSAGES: JET should be considered in adults presenting with postoperative narrow-complex tachycardia and atrioventricular dissociation. Accurate electrocardiogram interpretation is essential for appropriate management.
