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

Video Transcription

Video Summary

The transcript discusses the detection of conduction block in cardiac procedures. Initially, the activation pattern suggests block, but isn’t definitive. Increasing the pacing rate helps reveal clearer patterns indicative of block. Persistent conduction is suspected despite extensive ablation efforts. Non-inducibility of atrial flutter isn't reliable for confirming block, as it often leads to a high recurrence rate. Factors like using adenosine can reveal dormant conduction, indicating no block. Adjustments in recording locations or catheter use offer limited insights. Thus, pacing faster can expose the lack of block, highlighting the need for cautious assessment in flutter ablation procedures.
