Learn a systematic approach to management of wide complex tachycardia that doesn't rely on exact rhythm identification or scoring systems with guest Dr. Kevin Butler. By understanding the physiology rather than memorizing a score or algorithm you can use Kevin's approach and ABCD mnemonic to help differentiate between ventricular tachycardia, SVT with aberrancy, and other arrhythmias. Learn how not to miss the vital mimics with his SPAM filter. And finally by understanding which treatments are safe and which treatments potentially dangerous you can understand how to move forward even when you're not exactly sure what the arrhythmia is. Whether you're an EMT, paramedic, or emergency physician, this episode provides the essential principles and stepwise strategies to ensure effective and safe patient management. 00:00 Introduction to Arrhythmia Management 00:29 Personal Anecdote: Lessons from Paramedic School 02:04 Introducing Dr. Kevin Butler 02:16 Sponsor Message: The Recess Tailor 03:35 Welcome to EMS Cast 04:04 Understanding Wide Complex Tachycardia 05:37 Approach to Arrhythmia Management 07:02 Principles of Managing Wide Complex Tachycardia 08:39 Pathophysiology of Wide Complex Tachycardia 18:30 Identifying and Treating Mimics 26:55 Regular vs. Irregular Wide Complex Tachycardia 29:59 Understanding Torsades and Its Management 30:25 Identifying Atrial Fibrillation with Pre-Excitation 32:14 Treatment Considerations for AFib with WPW 35:02 Distinguishing Between VT and SVT with Aberrancy 37:09 Physiological Approach to ECG Interpretation 40:24 ABCD Mnemonic for VT Diagnosis 47:49 EMS Treatment Protocols for Wide Complex Tachycardia 51:54 Pre-Hospital Cardioversion Tips 55:22 Emergency Department Approach to Wide Complex Tachycardia 58:00 Final Thoughts and Key Takeaways Resources • The Resus Tailor • Episode Blog Post with EKG examples • Survey- Help us learn what content you want Gear We Like • Good Stethoscope - https://amzn.to/3YJJrf2 • Good Shears - https://amzn.to/40FROuF or https://amzn.to/3ChZ4Tn • Notepad for taking notes on calls - https://amzn.to/3Z1X21J • Sunglasses - https://frontline-optics.com/discount/EMSCAST15 • Books we recommend - • The Dichotomy of Leadership - https://amzn.to/4fiCAjN • Extreme Ownership - https://amzn.to/3O1FWfa • Managing the Unexpected: Sustained Performance in a Complex World - https://amzn.to/3V7BwYf • Thinking Fast and Slow - https://amzn.to/4fiJG85 • A Thousand Naked Strangers: A Paramedic's Wild Ride to the Edge and Back - https://amzn.to/3YJJrf2 Guest/Cast/Crew information- Guest- Dr. Kevin Butler, Emergency Physician, Lead Instructor for DHREM's EKG didactic curriculum Host- Ross Orpet, Will Berry Catch up with us after the show • Instagram- @emscast • Twitter- @ems_cast • Website- www.emspodcast.com • Want to stay ahead of the top 1% in EMS and build real confidence in the field? 👉 Book a call to get personalized guidance, improve decision-making under pressure, and grow your skills as a paramedic: emspodcast.com/free-coaching-call 📰 Join our weekly newsletter for exclusive EMS insights, leadership strategies, real-life scenarios, and tools designed to help you stay sharp, confident, and ahead of the curve: https://loudandclear.kit.com/d45b012fae • American Burn Association / ABLS: Enter the ABLS giveaway by June 30, 2026; the winner will be selected July 1, 2026.
