(FIT)-Module 3 Workshop 4: SVT and VT Invasive and Non-Invasive Correlation-Miles Case 1 Answer

Video Transcription

Video Summary

The patient exhibits both orthodromic AV re-entry and typical AV node re-entry. Analysis shows two different tachycardias: one with a short VA interval indicating AV node re-entry and another with a longer VA interval, suggesting AV re-entry using a retrogradely conducting left free wall pathway. Both tachycardias display a right bundle branch block morphology, ruling out ventricular or pre-excited tachycardias. The strategy involves evaluating the significance of each tachycardia and potentially performing ablations on both, as they were both considered inducible and likely important in this case.
