This article reports that contrary to prevailing opinion, adenosine may be useful for the termination of ectopic atrila tachycardia, particularly in older adults, according to data from a...
Due to triggered activity, it also terminates many focal atrial tachycardias and ventricular arrhythmias. Since it induces conduction block in the AV node, adenosine has diagnostic utility in patients with narrow QRS complex tachycardia. Similarly, adenosine could be of the most value in ...
Atrial tachycardia (AT) can originate from the proximal coronary sinus (CS). However, detailed electrophysiologic characteristics of the tachycardia are not available. We describe the electrophysiologic characteristics, response to adenosine 5′-triphosphate, and results of radiofrequency ablation of AT ...
Background: Adenosine is considered safe and effective for paroxysmal supraventricular tachycardia (PSVT), but anecdotal experience suggests that adenosine can precipitate atrial arrhythmias. Objectives: To determine the frequency and mechanisms of adenosine-induced atrial arrhythmias. Setting: Clinical ...

A 65-year-old woman developed bronchospasm after receiving adenosine during atenolol therapy for atrial tachycardia. The woman presented to an emergency-department (ED) with narrow-complex tachycardia. She received an IV bolus of adenosine 6mg, followed by adenosine 12mg. Her tachycardia resolved, ...
Administration of adenosine also frequently results in atrial and ventricular extrasystoles that may terminate the tachycardia. Block during AV nodal conduction is also the usual mechanism for termination of AV reentrant tachycardia using an accessory pathway. Consistent with the known pharmacokinetic ...
Adenosine is therefore particularly suitable for the diagnosis of tachycardias and the acute management of PSVT involving the AV node in all age groups, without the risks of cardiac arrest and hypotension associated with verapamil. Furthermore, intravenous adenosine infusion may be used to induce ...
(IV) bolus followed by a saline flush can be helpful during a narrow complex tachycardia. This can terminate AVNRT (AV nodal reentry tachycardia) and sometimes atrial tachycardia as well. Adenosine will slow, not terminate, atrial fibrillation (AF) and atrial flutter, allowing an accurate ...
