2.22 Combination of statements
The program distinguishes six basic infarct locations: septal, anterior, lateral, high lateral,
inferior, and posterior. If infarction is present at different locations, the program attempts to
generate combined infarction statements. For instance, the statements “inferior infarct” and
“posterior infarct” will be combined in the statement “inferoposterior infarct.” The degree of
probability of the combined infarct is equal to the highest degree of the separate infarcts.
Thus, “probable” infarct and “possible” infarct will combine to “probable.” The following
combinations can be made:
“inferior”+“posterior”  “inferoposterior”
“posterior”+“lateral”  “posterolateral”
“inferior”+“lateral”  “inferolateral”
“inferior”+“posterior”+“lateral”  “inferoposterolateral”
“high lateral”+“lateral”  “high-lateral and lateral”
“anterior”+“lateral”  “anterolateral”
“anterior”+“lateral”+“high lateral”  “anterolateral and high-lateral”
“anterior”+“septal”  “anteroseptal”
“anterior”+“septal”+“lateral”  “extensive anterior”
“anterior”+“septal”+“lateral”+“high lateral”  “extensive anterior and high-lateral”
A similar procedure is followed for combining repolarization disturbances or ST elevation at
different locations. For these abnormalities, locations “septal”, “anterior”, and “lateral” are
renamed “right precordial”, “mid precordial”, and “left precordial”, respectively. The locations
in the combined statements are adjusted accordingly.
