165: Breaking the Storm Part 2: Antiarrhythmics, Sympathetic Blockade, and the Emerging Role of Esmolol
About this episode
This episode explores the physiology and pharmacology of recurrent V-fib and the role of various antiarrhythmics in treatment.
The shock worked. The rhythm converted. And then V-fib came right back. Now what? Part two of this series explores the physiology and pharmacology driving recurrent V-fib so you can respond confidently when shocks aren’t enough. You'll learn how the body's sympathetic nervous system response keeps the heart unstable, why epinephrine can both help and hurt, when to reach for lidocaine over amiodarone, and what the research says about the emerging role of esmolol to target the storm itself (not just the arrhythmia). Topics discussed in this episode: The sympathetic nervous system and cardiac arrest Why epinephrine both helps and hurts Amiodarone vs. lidocaine: which is better? Key findings from the ROC-ALPS trial Why antiarrhythmics don't replace defibrillation The evidence behind esmolol in refractory V-fib 3 lessons for codes when ACLS isn't enough Mentioned in this episode: CONNECT 📸 Connect on Instagram: https://www.instagram.com/therapidresponsern/ 📚 Check out my course: https://www.rapidresponseandrescue.com/learnmore 🧑💻Check out my website: https://www.rapidresponseandrescue.com/ 📬 Subscribe to my newsletter: https://www.rapidresponseandrescue.com/login 🎁 Affiliation…
