Many factors and technical problems may alter the interpretation of electrocardiograms (ECGs). Infrequently, an artifact is considered to be the cause of ST-segment elevation, especially in asymptomatic patients. An important difference between true ST-segment elevation attributable to myocardial infarction and an artifact is that the baseline elevation in an artifact may begin before or after the onset of the QRS complex. When one encounters an abnormal ECG that exhibits suspicious wave contours and possibly only one completely normal limb lead, the diagnosis of arterial pulse artifact should be considered.
许多因素和技术问题可能会改变心电图（ECG）的解读。偶尔，伪差被认为是ST段抬高的原因，尤其是在无症状患者中。因心肌梗死导致的真正ST段抬高与伪差之间的一个重要区别在于，伪差中的基线抬高可能在QRS波群起始之前或之后开始。当遇到一份异常心电图，其波形轮廓可疑且可能只有一个完全正常的肢体导联时，应考虑动脉搏动伪差的诊断。
