(FIT)-Module 2 Workshop 3: SVT Mechanisms and Maneuvers-Miller Case 2 Answer

Video Transcription

Video Summary

The transcript describes a diagnosis of antedromic atrioventricular reentry tachycardia during a wide complex tachycardia. It highlights the role of atrial extra stimuli, regular VV intervals, and the absence of ventricular electrograms, which exclude ventricular tachycardia. The consistent VA relationship contradicts atrial tachycardia and atrioventricular nodal reentry. An accessory pathway is possible but unlikely due to the short VA intervals in the CS recordings. Overall, antedromic SVT is deemed the most likely diagnosis among the options considered, although not definitively unique.
