(FIT)-Module 5 Workshop 8: Device Cases-Asirvatham Case 6 Question

Video Transcription

Video Summary

The discussion focuses on changes in pacing vectors between the LV lead and ICD lead, often influenced by different outputs. The location remains consistent, but output variations can alter the pacing axis, as seen with axis flips in specific ECG leads. This change might indicate lead migration, pacing-induced effects, or nodal stimulation. Understanding the relationship between low and high output scenarios could explain the observed morphology changes. The conversation raises questions about how different factors contribute to this phenomenon, potentially involving both new and existing pacing systems.
