Q

What are the Differences between PAC, PJC and PVC

A
  • A PAC is when you have another full contraction (heartbeat) (P, QRS, T) that starts right after you have already have a full contraction (heartbeat) (P, QRS, T).
    • A PVC, you will have a QRS complex that is greater than 0.12 seconds.
    • A PJC is a QRS complex that is 0.12 seconds or less, but does not have a P wave.
