Definition of st elevation

    • What can cause ST elevation?

      Other causes of ST elevation include (1): cardiac trauma ventricular aneurysm or large chronic myocardial infarct (at rest, exercise induced or aggravated) cardiomyopathies including hypertrophic cardiomyopathy left bundle branch block

    • What causes ST elevation?

      ST segment elevation in the setting a heart attack or in brugada syndrome is caused by early repolarization of the inner layer of the heart while the outer layer is repolarization -- it is a differential in repolarization times in the heart.

    • What is considered ST elevation?

      An ST elevation is considered significant if the vertical distance inside the ECG trace and the baseline at a point 0.04 seconds after the J-point is at least 0.1 mV (usually representing 1 mm or 1 small square) in a limb lead or 0.2 mV (2 mm or 2 small squares) in a precordial lead.

    • Why does ST elevation occur?

      ST segment elevation occurs because when the ventricle is at rest and therefore repolarized, the depolarized ischemic region generates electrical currents that are traveling away from the recording electrode; therefore, the baseline voltage prior to the QRS complex is depressed (red line before R wave).
