Clinical Consequences of Electrocardiographic Artifact Mimicking Ventricular Tachycardia

Abstract
Electrocardiographic artifact can simulate ventricular tachycardia. The literature regarding electrocardiographic artifact is limited to case reports,1-7 proposed classifications,8,9 and diagnostic criteria.10 There is little information regarding the clinical implications of the misdiagnosis of artifact as ventricular tachycardia. We describe 12 patients who underwent unnecessary diagnostic or therapeutic interventions as a result of such a misdiagnosis.
