Video Summary

In the video, the speaker discusses the basics of electro-anatomic mapping in the context of atrial and ventricular tachycardias. He explains that electro-anatomic mapping is a way of creating a 3D map of the heart's electrical activity. He emphasizes the importance of picking a stable and appropriate reference point for the mapping, as well as setting the activation window correctly to capture the earliest and latest signals. The speaker also advises using entrainment to confirm the origin and mechanism of the tachycardia before proceeding with ablation. He discusses the use of different mapping systems, such as CARDO and NAVX, and recommends using high-density mapping catheters like the PentaRay or Decanav for more accurate mapping. Finally, he touches on the use of voltage mapping to identify scar tissue and the importance of imaging, particularly in cases with complex anatomy or variants. Overall, the speaker provides a comprehensive overview of electro-anatomic mapping and offers practical tips for its successful application in clinical practice.
