Junctional: Summary of Characteristics

What are the characteristics of PJCS?

Rhythm: Irregular because of premature beats
Rate: Usually within normal range but depends on underlying rhythm
P waves: May occur before, during, or after the QRS; if visible, P wave is inverted
PR Interval: If a P wave occurs before the QRS, the PR interval will usually be 0.12 sec or less; if no P wave occurs before the QRS, there will be no PR interval
QRS: 0.11 sec or less unless abnormally conducted

What are the characteristics of Junctional escape beat?

Rhythm: Irregular because of early beats

PR Interval: 0.12 to 0.20 sec and constant from beat to beat
QRS: 0.11 sec or less
