It means that the ST segment of the EKG is either above the baseline by 0.9mm or below it by 1.1mm in the leads that are identified. Typically, when it is only in one lead like that, the diagnosis could be lead placement. But, your cardiologist should interpret these results based on your clinical situation. So, see your cardiologist to review these findings. Good luck to you!
