Premature Junctional Contractions (PJCs) are early heartbeats that originate from the AV junction instead of the SA node. In this video, we break down PJC ECG features, causes, clinical significance, and how to quickly identify them on an ECG strip — all in a simple, exam-oriented way.

You’ll learn:
• What causes PJCs
• How PJC looks on ECG
• How to differentiate PJC from PACs
• Nursing and NCLEX key points

Perfect for NCLEX, cardiac monitoring, and ECG beginners.

🔑 PRO TIPS (NCLEX MUST-KNOW)

✔ P wave may be absent, inverted, or appear after QRS
✔ QRS is usually narrow (more then 0.12 sec)
✔ Rhythm is usually irregular due to early beats
✔ Often caused by digoxin toxicity, ischemia, or electrolyte imbalance
✔ PJCs are usually benign if infrequent
✔ Treat the underlying cause, not the rhythm itself

💡 NCLEX Pearl:
If QRS is narrow + P wave inverted or missing → think junctional origin!
