AB Although  vasodepressor  syncope  is  the  most  common  cause  of  syncope  in  older  children  and  adolescents,  cardiac  causes  are  the  most  concerning  and  life  threatening  in  this  group.  Approximately  2–6%  of  all  cases  of  pediatric  syncope  can  be  attributed  to  the  heart.  The  rare,  yet  life-threatening  causes  of  syncope  must  be  discriminated  from  more  benign  etiologies.  History,  physical  examination  findings,  and  electrocardiograph  (ECG)  findings  can  be  used  by  the  emergency  medical  practitioner  to  screen  for  patients  who  may  be  at  risk  for  cardiac  pathology.  Historical  “red  flags”  include  syncope  with  exertion  and  a  positive  family  history  (Table  18–1).  Cardiac  causes  of  syncope  can  be  divided  into  structural,  functional,  and  primary  electrical  categories.  Table  18–2  lists  ECG  findings  associated  with  specific  cardiac  abnormalities.
