(FIT)-Module 2 Workshop 2: Entrainment and SVT Maneuvers-Stevenson Case 6 Answer

Video Transcription

Video Summary

The transcript explains the identification of a cardiac reentry circuit using a schematic and tracing. It describes how site D in the central isthmus is likely part of the reentry circuit, indicated by a stim to QRS interval of 200 milliseconds. This site fits well for producing entrainment with concealed fusion. The tracing shows pacing stimuli leading to ventricular tachycardia, and the challenge is confirming the site's involvement using the post-pacing interval and stim to QRS insights. Site D aligns most appropriately with the observed characteristics, suggesting it's within the reentry circuit.
