Can a Premature Junctional Contraction Kill You?

What is a Premature Junctional Contraction on ECG and Can a Premature Junctional Contraction Kill You?

The discussion focused on identifying and analyzing premature junctional contractions (PJCs), distinguishing them from arrhythmias. Key features include the absence of a P wave before the QRS complex, a flat ST segment, and a PR interval less than 0.12 seconds. Digoxin, used to treat atrial fibrillation and flutter, was detailed for its effects on conduction, including slowing the AV node and causing a "mustache" on the ECG. Digoxin toxicity symptoms include confusion, vision changes, nausea, and arrhythmias except atrial fibrillation. Risk factors for toxicity include drug interactions, hypokalemia, and certain conditions. Treatment involves recognizing toxicity, stopping digoxin, and administering digibind if available.

Hey Nurseminder Nation, as a nursing student, LPN, or Registered nurse developing your nursing skills around ECG interpretation and treatment is a must. Not only will it add to your confidence as a nurse, it will add to a better nursing life.

The nurse skills today will answer the question "What is a Premature Junctional Contraction on ECG?"

Premature junctional contraction on ECG may also be called a premature junctional complex and learning how to identify junctional rhythm is important to understanding how we treat junctional rhythms. One consideration is digoxin and the moustache presentation on ECG when a patient has digoxin toxicity
