Does intravenous adenosine cause atrial fibrillation with rapid conduction over an accessory pathway in patients with regular, narrow QRS tachycardia?
Intravenous adenosine for PSVT can induce life-threatening atrial fibrillation with rapid conduction over an accessory pathway.
Adenosine is well known as a safe and effective drug for the termination of paroxysmal supraventricular tachycardia (PSVT), and is also widely used for the termination of both narrow and wide QRS-complex tachycardia of unknown origin in the setting of hemodynamic stability. However, due to a shortening of atrial refractoriness, adenosine can facilitate the induction of atrial fibrillation. A life threatening tachycardia may result from a potential rapid conduction of the atrial fibrillation over an accessory pathway. A case of patient, where the intravenous administration of adenosine, during regular, narrow QRS tachycardia, was followed by atrial fibrillation with rapid conduction over a manifest accessory pathway, is reported.

Shim et al. (Wed,) conducted a case report in Supraventricular Tachycardia with Wolff-Parkinson-White syndrome (n=1). Intravenous Adenosine was evaluated on Development of atrial fibrillation with rapid ventricular pre-excitation. Intravenous administration of adenosine for supraventricular tachycardia induced life-threatening atrial fibrillation with rapid conduction over a manifest accessory pathway.
