The event
Q_Assessment_Abnormal_IMI
is used to characterised the symptoms
of Acute_inferior_MI symptoms. A set of guards are used to satisfy the required
condition for the symptoms of Acute_inferior_MI. A list of guards state that the si-
nus rhythm is
Ye s
, the ST elevation is TRUE and the length of ST segment elevation
is greater than or equal to 1000 µm in two or more leads (II, III, aVF), or the ST
elevation is TRUE and the length of ST segment elevation is greater than or equal
to 1000 µm in two or more contiguous pre-cordial leads V1 to V6, the width of
Q-wave is greater than or equal to 40 ms and the depth of Q-wave is greater than or
equal to 3000 µm in lead II, the width of Q-wave is greater than 40 ms and the depth
of Q-wave is greater than or equal to 7000 µm in lead III, the width of Q-wave is
greater than or equal to 40 ms and the depth of Q-wave is greater to 3000 µm in lead
aVL, and the normal state of the Q-wave is FALSE.
