Key result
Intravenous adenosine slowed the atrial rate in two patients with sinus node reentrant tachycardia and terminated the tachycardia in one.
Why the study?
Does intravenous adenosine affect atrial rate or terminate sinus node reentrant tachycardia?
Case Report (n=2)
Does intravenous adenosine affect atrial rate or terminate sinus node reentrant tachycardia?
Adenosine slows atrial rate and can terminate sinus node reentrant tachycardia, suggesting sinus nodal tissue involvement in the tachycardia circuit.
No takes yet. Share an insight, caveat, or question.
Adenosine response may aid sinus node reentrant tachycardia diagnosis; leaves open confirmation in larger trials before clinical use.
Griffith et al. (1989) conducted a case report in sinus node reentrant tachycardia (n=2). Adenosine was evaluated on atrial rate and tachycardia termination. Intravenous adenosine slowed the atrial rate in two patients with sinus node reentrant tachycardia and terminated the tachycardia in one.
