Horizontal ST depression

Horizontal ST segment depression occurs when the baseline is depressed between the end of the QRS complex and the start of the T wave. There are many causes. Horizontal ST depression in 2 or more contiguous leads suggests myocardial ischemia. If present, look very closely fro ST elevation in the opposite (reciprocal) leads. Horizontal ST depression in V1-3 may be caused by acute posterior infarction.
