Adenosine and supraventricular tachycardia.

J P DiMarco

    Progress in Clinical and Biological Research
    |January 1, 1987
    PubMed
    Summary

    Adenosine effectively terminates paroxysmal supraventricular tachycardia (PSVT) by impacting the AV node. Further research aims to explore its mechanisms and develop long-acting adenosine analogs for chronic arrhythmia management.

    Area of Science:

    • Clinical Electrophysiology
    • Cardiovascular Pharmacology

    Background:

    • Adenosine is recognized for its potent electrophysiologic effects on the heart.
    • Its role in managing supraventricular tachycardias requiring atrioventricular (AV) nodal conduction is established.

    Purpose of the Study:

    • To summarize the established and potential uses of adenosine in treating and diagnosing supraventricular tachycardias.
    • To highlight preliminary findings on adenosine's safety and efficacy.
    • To outline future research directions for adenosine in arrhythmia management.

    Main Methods:

    • Review of existing laboratory and clinical investigations on adenosine's electrophysiologic effects.
    • Analysis of preliminary data on acute intravenous adenosine administration.
    • Identification of current therapeutic limitations and future research needs.

    Main Results:

    • Adenosine is effective in terminating episodes of PSVT dependent on AV nodal conduction.
    • It serves as a diagnostic tool to reveal underlying atrial mechanisms in refractory arrhythmias.
    • Preliminary data indicate acute intravenous adenosine is safe and highly efficacious.

    Conclusions:

    • Adenosine is a valuable therapeutic and diagnostic agent for specific supraventricular tachycardias.
    • Systematic comparative data with other therapies are currently lacking.
    • Future research should focus on elucidating arrhythmia mechanisms and developing improved adenosine formulations for chronic use.
