Episode 26: Adenosine and Wolff-Parkinson-White (WPW)

April 1st, 2026

In this episode, Dusty King and Medical Director Jonathan Apfelbaum break down adenosine in a practical, field-ready way. They review how the medication works at the AV node, when it is appropriate for narrow-complex regular tachycardia, and why Wolff-Parkinson-White (WPW) does not automatically rule it out. The conversation also highlights patient preparation, what to expect after administration, key contraindication concerns, and how to think through WPW with atrial fibrillation versus regular Supraventricular Tachycardia (SVT).
