This video reviews basic principles of atrial anatomy, identifying and localizing atrial flutter, mapping and ablation, with a heavy focus on electrograms, activation sequence, and entrainment. I review ways to ensure an intact line of block, focusing on use of different catheters and avoiding pitfalls that could lead to error. I hope you enjoy the presentation!
