What are the characteristics of flutter waves. How do you tell the difference in atrial fibrillation and atrial flutter? All of this takes practice. You can learn it!.

What is a PAC? Is it a premature atrial contraction? (Yes it is). After the PAC, what do you normally see on the EKG? (is it a pause?...Yes)
Practice your PAC interpretations using Dr. Kravitz Worksheets. Always state the Underlying rhythm and then note where the PAC is. For example, NSR with a PAC (5th complex).
