Key result
Adenosine administration in a patient with atrial flutter treated with metoprolol and diltiazem resulted in prolonged complete heart block requiring intubation and temporary pacing.
Case Report (n=1)
Adenosine administration in patients on combination AV nodal blocking agents (metoprolol and diltiazem) can lead to severe, prolonged complete heart block requiring pacing.
May warrant caution with adenosine in atrial flutter on AV nodal blockers; leaves open need for systematic safety data.
Adenosine is a purine nucleoside widely used to terminate supraventricular tachycardias, and as a diagnostic adjunct in narrow complex regular tachycardia of uncertain origin. Atrioventricular blockade and bradyarrhythmias following administration are common but generally short-lived. We report a case of prolonged complete heart block requiring intubation and temporary pacing, following adenosine administration in atrial flutter treated with combination metoprolol and diltiazem.

Harvey et al. (2007) conducted a case report in Atrial flutter (n=1). Adenosine was evaluated on Prolonged complete heart block requiring intubation and temporary pacing. Adenosine administration in a patient with atrial flutter treated with metoprolol and diltiazem resulted in prolonged complete heart block requiring intubation and temporary pacing.
