Session II: Invasive Diagnosis and Treatment-6154-Techniques of Differentiating SVT Mechanisms- Part I

Video Transcription

Video Summary

Dr. Greg Michaud from Vanderbilt University gives a comprehensive lecture on the diagnosis of supraventricular tachycardia (SVT). He discusses the common types of SVT, including AV nodal re-entry, AVNRT, and AVRT. The lecture also covers atrial tachycardia and less common forms of SVT such as accessory pathways and fascicular tachycardia. Dr. Michaud emphasizes the importance of accurate observations and specific maneuvers to correctly identify the mechanism of SVT. The lecture goes into detail on the use of sinus rhythm, pacing maneuvers, retrograde atrial activation sequence, and differential RV pacing to determine the mechanism of SVT. Dr. Michaud also mentions the use of adenosine for diagnosis and discusses the significance of VA block during ventricular pacing. The complexity of diagnosing SVT is highlighted, and a systematic approach is recommended to accurately identify the type of tachycardia. The video provides a comprehensive overview of the diagnosis of SVT and the techniques and observations used in the process.
