(FIT)-Module 2 Workshop 3: SVT Mechanisms and Maneuvers-Miller Case 1 Answer

Video Transcription

Video Summary

The transcript discusses the risks and observations in a cardiac procedure involving radiofrequency (RF) ablation. It highlights noticing pre-excitation and changes in electrograms, with emphasis on the gradual loss of the delta wave and the presence of an accelerated junctional rhythm. Concerns are raised about potentially causing heart block while trying to eliminate pre-excitation due to irritation of the normal conduction system. The recommended approach is to pace the atrium to determine pre-excitation status and preserve normal AV conduction before proceeding with RF application to avoid complications.
