NCI: EKG ST segment elevation is usually attributed to impending infarction, but can also be due to pericarditis or vasospastic (variant) angina and early repolarization. In some healthy young adults, a form of ST elevation can be normal. The height of the ST segment is measured at a point 2 boxes after the end of the QRS complex. ST segment elevation is considered significant if it exceeds 1 mm in a limb lead or 2 mm in a precordial lead.,NCI: An electrocardiographic finding of ST segment elevation above the baseline.,NCI: An electrocardiographic finding of ST segment elevation above the baseline. (NCI),NCI: Evaluation of the interval from the end of ventricular depolarization to the onset of the T wave; it is usually isoelectric in normal subjects.
