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

Video Transcription

Video Summary

The video explains a diagnosis of AV nodal reentry tachycardia based on an analysis of pacing intervals. The speaker discusses identifying a pseudo-VAAV pattern by noting which atrial activations are controlled by ventricular stimuli. By comparing pacing at 440 milliseconds with the tachycardia cycle at 465 milliseconds, they highlight a crucial interval measurement of 440 milliseconds. The post-pacing interval and S to A minus V to A values suggest either a slow accessory pathway or, more likely, atypical AV nodal reentry, confirming the diagnosis.
