[PMID 20003123] Chang M, et al.

In the peripheral line group, tachycardia was terminated in 70% of patients who got 6 or less mg of adenosine.

Objective: To assess the safety and efficacy of intravenous adenosine in terminating acute episodes of paroxysmal supraventricular tachycardia. Keywords: Further randomized control studies should be completed to validate these results.”.

Interesting electrophysiological findings in a patient with coexistence of atrial tachycardia originating from coronary sinus and slow-fast atrioventricular nodal reentrant tachycardia. Adverse reactions to adenosine are common but are minor and brief. Again, the patient converted for a brief time but then reverted back to SVT.

High-dose adenosine for treatment of refractory paroxysmal supraventricular tachycardia. If this is not successful, my next agent would be a calcium channel blocker, as adenosine gives patients a sense of impending doom. Adenosine dose should be less when administered through a central line. [Link is. DiMarco JP(1), Miles W, Akhtar M, Milstein S, Sharma AD, Platia E, … It represents a subset of SVT, an umbrella term used to describe tachycardias involving tissue from the His bundle or above.1 The 3 most common types of PSVT are atrioventricular nodal reentrant tachycardia (AVNRT), atrioventricular reciprocating tachycardia (AVRT), and atrial tachycardia (AT).2 Treatme… Because adenosine decreases conduction through the AV node, first-, second-, or third-degree heart block are possible effects. In this episode, I’ll discuss why the adenosine dose is reduced by 50% when it is given in a central line.  |  Adenosine has recently become widely available for the treatment of paroxysmal supraventricular tachycardia.

If a patient develops a high-level block after the initial dose of adenosine, subsequent doses should not be given. Your post made me think about that and wonder if given the rapid t1/2 if pts with very poor EFs/severe heart failure have different responses to particularly the lower recc doses?

Hi Ash! Now check your email to confirm your subscription. Case report: Adenosine is a purine nucleoside that impairs conduction through the AV node and is thus effective in terminating tachycardias involving the AV node. This is in addition to collaborating with an expert in cardiac electrophysiology when initial management tactics are not successful.

In over 10% of adult patients, PSVT will not be terminated with maximum doses of adenosine. stopcock, single-port IV, two-port IV, etc), Did not exclude patients who may have received additional rate controlling medications prior to adenosine administration, which could also confound results, As with anything in medicine, it is important to have respect for the scientific method and although the authors should be applauded for this study, their numbers are too small, and this paper should be looked at as initial data that requires further research.
