(FIT)-Module 3 Workshop 4: SVT and VT Invasive and Non-Invasive Correlation-Miller Case 2 Answer

Video Transcription

Video Summary

The process involves conducting electrical signals from the left superior pulmonary vein to the atrium, then to the right superior pulmonary vein, which becomes unisolated. Sinus rhythm is present without potentials in these veins, but effects are observed only later. Adenosine induces AV block, capturing potentials and traveling between veins. The left superior pulmonary vein exits and the right superior vein allows entry, both losing isolation. After a few cycles, the right superior vein stops, but the left continues activating the atrium. This indicates a failure to maintain antral block in both veins.
