In-Depth Information
The next event QRS_Test_Atypical_RBBB_Brugada_Syndrome is used to trace
the symptoms of Brugada Syndrome. The guards of this event presents that the
heart is in state of Atypical RBBB, QRS interval is greater than or equal to 110 ms,
slurred S-wave is FALSE in leads V5 and V6, the heart has not the symptoms of
WPW syndrome and the possibility of any other diseases, ST elevation is TRUE in
leads V1 and V2, and the sinus rhythm is Ye s .

The event QRS_Test_Atypical_RBBB_RV_Dysplasia captures the diagnosis pro-
cess for Right Ventricular Dysplasia (RV Dysplasia), where a set of guards ex-
plores the required symptoms using predicates. These predicates express that the
heart is in state of Atypical RBBB, QRS interval is greater than or equal to
110 ms, the heart has not the symptoms of WPW syndrome, Brugada Syndrome
and the possibility of any other diseases, and epsilon wave is TRUE in leads V1
and V3.
