(FIT)-Module 3 Workshop 5: Invasive and Non-Invasive Correlation-Marchlinski Case 6 Answer

Video Transcription

Video Summary

The video transcript describes the conduction pattern following adenosine administration in a cardiac study. The conduction occurs from the left inferior pulmonary vein to the surrounding left atrium, with sinus rhythm and left superior pulmonary vein pacing. Adenosine shows conduction from the left superior to the left inferior pulmonary vein, activating the coronary sinus (CS) distally to proximally. This pattern repeats with left superior pulmonary vein pacing, indicating a reconnection and similar conduction pathway. Both treatments show activation from the left superior to the left inferior pulmonary vein, exiting and activating the CS in a consistent manner.
