(FIT)-Module 6 Lectures: Special Technology Sessions-Cardiac Conduction System Pacing

Video Transcription

Video Summary

The lecture on "Cardiac Conduction System Pacing: Theory and Practice" emphasized the importance of understanding cardiac conduction anatomy for effective pacing. His bundle and left bundle branch pacing were discussed as alternative methods to traditional pacing, offering potential benefits in correcting conduction blocks and improving cardiac function, especially in patients with heart failure or high pacing burdens.<br /><br />His bundle pacing can restore normal conduction and QRS morphology in conditions like complete heart block or bundle branch blocks. Non-selective and selective pacing techniques were explained, highlighting the challenges of high capture thresholds and lead placement.<br /><br />Left bundle branch pacing, seen as advantageous due to a broader target zone, might provide more stable thresholds and better procedural feasibility, also addressing limitations observed in his bundle pacing. This method is particularly promising for patients with conduction diseases like left bundle branch block, offering better synchronization and potentially superior outcomes compared to biventricular pacing.<br /><br />The lecture reviewed clinical studies supporting these conduction system pacing methods, particularly in reducing heart failure hospitalizations and improving ejection fractions. Updated guidelines recommend incorporating these pacing strategies, with ongoing trials expected to further define their role in clinical practice.
