Key result
Electrophysiologic evaluation of two adults with spontaneous junctional ectopic tachycardia showed mechanistic heterogeneity, with one case of triggered activity and one of abnormal automaticity.

Adult JET mechanisms may dictate adenosine response; case reports leave open mechanism-specific therapy trials.
Case Report (n=2)
Spontaneous junctional ectopic tachycardia in adults can be caused by multiple mechanisms, including triggered activity and abnormal automaticity, which respond differently to adenosine.
Liu et al. (2011) conducted a case report in Junctional ectopic tachycardia (JET) (n=2). Electrophysiologic and pharmacologic maneuvers was evaluated on Electrophysiologic mechanism of tachycardia. Electrophysiologic evaluation of two adults with spontaneous junctional ectopic tachycardia showed mechanistic heterogeneity, with one case of triggered activity and one of abnormal automaticity.
