Electrocardiograms (ECGs) can be affected by various factors and technical problems. It is rare for an artefact to be the cause of ST-segment elevation, especially in asymptomatic patients. An important distinction between true ST segment elevation caused by myocardial infarction and an artefact is that the baseline elevation in an artefact may begin before or after the appearance of the QRS complex.
