Premature Junctional Contraction

Aka: Premature Junctional Contraction, PJC
  1. See Also
    1. Extrasystole
  2. Causes
    1. Same as for Premature Atrial Contractions
  3. Signs: EKG Findings
    1. Inverted P Wave (retrograde) if present
    2. Narrow complex if high nodal source
    3. Wide complex if lower nodal source

Junctional premature complex (disorder) (C0428981)

Definition (NCI) An electrocardiographic finding of an ectopic impulse originating in the AV junction presenting as a QRS complex of supraventricular origin which is not preceded by a P wave. (CDISC)
Definition (NCI_CDISC) An electrocardiographic finding of an ectopic impulse originating in the AV junction presenting as a QRS complex of supraventricular origin which is not preceded by a P wave.
