In the presence of ST elevation, repolarization disturbance statements at corresponding
locations are suppressed. ST depression and ST elevation are considered to be mirror
images, taking the inferior location to be mirrored in the other localizations and vice versa. For
instance, if an inferior ST elevation is present as well as an high-lateral repolarization
disturbance without high-
lateral infarct, the statement “high-lateral ST depression” is
generated, further high-lateral repolarization statements being suppressed. Similarly, the
statements “right-precordial ST depression”, “mid-precordial ST depression”, “left-precordial
ST depression
”, and “inferior ST depression” can be generated.
