![]() Normal QRS complexes within the artifact.Absence of hemodynamic deterioration during the event.Characteristics that can help in differentiate an artifact from ventricular tachycardia include :.It is important to differentiate these, as misdiagnosis can lead to inadvertent use of medications and procedures in such a patient. Sometimes, EKG changes may mimic specific arrhythmias like ventricular tachycardia and atrial flutter or fibrillation. These changes can be misinterpreted as myocardial ischemia or infarction.ĭifferentiating an Artifact from Ventricular tachycardia If ST segments are affected by artifacts, either ST segment depression or elevation can occur on the EKG. ![]() It is important to differentiate these artifactual changes from genuine changes to prevent misdiagnosis. Most of the time, they are easily identifiable and neglected as they do not resemble any specific pattern. The table includes data from references Identification Īrtifacts can distort individual or all components (P, QRS, T waves and PR and ST segments) on the EKG.
