When vagal maneuvers fail to terminate stable narrow-complex SVT, the primary medication of choice is adenosine. For the unstable patient with a regular and narrow QRS complex, adenosine may also be considered prior to synchronized cardioversion.

Nov 9, 2015 · Consider a postural modification (leg elevation and supine positioning) to the Valsalva maneuver to improve the conversion rate. Consider applying defibrillation pads prior to the administration of adenosine. The drugs Dipyridamole (Persantine) and Carbamazepine (Tegretol) can potentiate adenosine.

Jun 7, 2018 · When a patient is in Paroxysmal Supraventricular Tachycardia or having Wolff-Parkinson-White Syndrome, you will want to administer Adenosine in a rapid bolus to slow down the heart to allow the electrical rhythm to reset.

Vagal maneuvers and adenosine are recommended (moderate-quality evidence) for the termination of regular SVT of uncertain type, atrioventricular nodal reentrant tachycardia, and atrioventricular reentrant tachycardia.

Dec 13, 2018 · Due to adenosine’s transient negative dromotropic effects on atrioventricular nodal conduction, it is an ideal agent to initially assess for the presence of a concealed, nondecremental AP in patients with supraventricular tachycardia.

Oct 11, 2012 · This article reviews a systematic approach to diagnosis and management of supraventricular tachycardias. Adenosine, which blocks the AV node, is of diagnostic value but should not be used in...

Comparative studies have shown that adenosine is as effective as verapamil in the treatment of supraventricular tachycardia, and has less potential for adverse effects. Patients with supraventricular tachycardia should initially be treated using vagotonic physical maneuvers.

Jul 11, 2023 · Adenosine is an endogenous compound that transiently blocks the adenosine A1 receptor leading to atrioventricular (AV) nodal blockade. 1 European and American guidelines recommend adenosine as a first-line pharmacotherapy in hemodynamically stable supraventricular tachycardia (SVT) in the setting of failed vagal maneuvers. 1,2 Common ...

Adenosine is the primary medication used in the treatment of SVT 2020 ACLS guidelines recommends adenosine 6 mg given as a rapid IV push followed by 12 mg if cardioversion unsuccessful (after vagal maneuvers have been attempted)

Mar 7, 2025 · Adenosine/ATP terminates paroxysmal supraventricular tachycardia (PSVT) in acute treatment by inhibiting atrioventricular (AV) node conduction, with rapid and transient effects and very short half-lives.
