This video starts with the basic principles of activation mapping for those new to the concept (I recommend everyone listen to the introduction and first few slides), proceeds (at 26:52) to use a simplified conduction model to describe common scenarios where activation mapping can be misleading, and culminates (at 50:36) in the more complex topic of creating a window of interest. In the latter discussion, I review specific situations that are the most problematic with regard to the creation of an activation map, and how to navigate a tough case where activation mapping is not helping. I hope you enjoy the presentation!
