	*P wave is either:
	**Absent
	**Abnormal with PR < 120ms
	**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 abnormal, may have RBBB morphology

	~~==Clinical Significance==~~
	*Less common than PVCs or PACs		*Less common than PVCs or PACs
	*Differentiate from [[WPW]] (short PR)		*Differentiate from [[WPW]] (short PR)
	*May be seen in healthy individuals with no clinical significance		*May be seen in healthy individuals with no clinical significance

			==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
