Stevenson Case 8 Question

Video Transcription

Video Summary

Case 8, a 74-year-old male with prior myocardial infarction and recurrent ventricular tachycardia is referred for catheter ablation. During endocardial catheter mapping, the tracing shown is recorded. Pacing to entrain tachycardia from the ablation catheter at this site is most likely to reveal which one of the following, A, post-pacing interval equaling the tachycardia cycle length, B, the VT exit site, C, a VT outer loop site, and D, an indeterminate response to entrainment.
