Popis: | Junctional ectopic tachycardia (JET) is a tachyarrhythmia arising from the atrioventricular node and His bundle area. Enhanced normal automaticity has been postulated as the mechanism of JET in the majority of patients. It is more common in children and can be seen as congenital or in postoperative settings. It is often a narrow complex tachycardia but can present as a wide complex tachycardia as a result of aberrant conduction. Its differentiation from other arrhythmias especially atrioventricular nodal reentrant tachycardia (AVNRT) can be challenging. Medical treatment of JET is difficult, and catheter ablation remains the mainstay of treatment in refractory cases with a high risk of atrioventricular block and recurrence. Junctional ectopic tachycardia is often a narrow complex tachycardia due to enhanced normal automaticity and its differentiation from other arrhythmias especially AVNRT can be challenging. Since existing diagnostic tests have limitations to differentiate it from other arrhythmias, the diagnosis should be made based on both clinical and electrophysiologic findings. |
