It is very important to recognize these artifacts, otherwise they can lead to unnecessary testing and therapeutic interventions. As a result of artifacts, normal components of the EKG can be distorted. 3.2.1 REVERSE mnemonic: Approach to EKG artifacts Įlectrocardiograph (EKG) artifacts are defined as EKG abnormalities, which are a measurement of cardiac potentials on the body surface and are not related to electrical activity of the heart.3.1 Differentiating an Artifact from Ventricular tachycardia.2.2.1 Medical equipment related EKG artifacts.Santosh Patel M.D., FRCA Associate Editor-In-Chief: Kashish Goel, M.D. Risk calculators and risk factors for EKG artifactsĮditor-in-Chief: C. ![]() US National Guidelines Clearinghouse on EKG artifactsĭirections to Hospitals Treating EKG artifacts Ongoing Trials on EKG artifacts at Clinical Ĭlinical Trials on EKG artifacts at Google Articles on EKG artifacts in N Eng J Med, Lancet, BMJ ![]()
