(FIT)-Module 4 Workshop 6: Electrocardiographic and Electrophysiological Correlations-Gerstenfeld Case 5 Answer

Video Transcription

Video Summary

The video discusses the effects of different saline concentrations and catheter types on lesion size during procedures. It highlights that using half normal saline results in larger lesions compared to normal saline due to its lower ionic concentration, which extends RF energy deeper into tissues. An 8mm catheter tip, although seemingly more powerful, actually results in smaller lesions than a 4mm tip because more energy is lost to blood flow. With half normal saline, larger lesions are achieved at the same power and duration compared to normal saline. The speaker concludes that option C is the correct answer.
