How can you tell the difference between a PAC, PVC, and a PJC? It's actually quite simple. Let's break these down.
- 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.
