==Background==
[[File:WPW and PJC.JPG|thumbnail|WPW with PJC underlined in red]]

*Less common than PVCs or PACs
*Differentiate from [[WPW]] (short PR)
*May be seen in healthy individuals with no clinical significance
**May also be seen in pathology such as [[valvular emergencies|valvular disease]], [[drug overdose|drug toxicity]], [[electrolyte abnormalities]]

==Clinical Features==
*Generally asymptomatic
*May cause palpitations

==Differential Diagnosis==
{{Palpitations DDX}}

==Evaluation==
*EKG
**P wave is either: Absent, Abnormal with PR < 120ms, '''OR''' Retrograde, which may be inverted in inferior leads
**PJC arrives before next sinus beat
**Followed by compensatory pause
**From AV node region, with ventricular response usually normal, so QRS complexes usually narrow
**If conduction is abnormal, may have right bundle branch block morphology

==Management==
*Depends on etiology and symptoms

==Disposition==
*Based on etiology and symptoms
