What are the characteristics of flutter waves. How do you tell the difference in atrial fibrillation and atrial flutter? All of this takes practice with your text and EKG assignments.

What is a PAC? Where does this ectopic beat come from? When reporting a PAC, remember to analyze the underlying rhythm and the underlying rate. After the PAC, what do you normally see on the EKG? (is it a pause?)
Practice in your text identifying PACs. What is a nonconducted PAC? What is NOT conducted in a nonconducted PAC?
