Key result
Adenosine offers diagnostic value for supraventricular tachycardias but should not be used in irregular wide-complex tachycardias because it may lead to clinical instability.
Why the study?
What is the systematic approach to the diagnosis and management of supraventricular tachycardias?
What is the systematic approach to the diagnosis and management of supraventricular tachycardias?
Adenosine is a valuable diagnostic tool for supraventricular tachycardias but is contraindicated in irregular wide-complex tachycardias.
Supports avoiding adenosine in irregular wide-complex tachycardias; leaves open need for randomized validation of SVT diagnostic utility.
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 cases of irregular wide-complex tachycardias, since it may lead to clinical instability.
