(FIT)-Module 2 Workshop 2: Entrainment and SVT Maneuvers-Stevenson Case 1 Answer

Video Transcription

Video Summary

The video discusses the mechanism of terminating ventricular tachycardia (VT) using pacing in a reentry circuit isthmus. Initially, VT is identified by two QRS complexes, followed by pacing which interrupts the tachycardia without a global capture. In a reentry circuit with a central isthmus, pacing captures a small myocardium area, blocking the exit wavefront while maintaining the antidromic wavefront within the circuit. This interruption terminates the tachycardia, confirming the pacing occurs in the reentry circuit isthmus.
