AB Dysrhythmias  are  classified  according  to  rate,  QRS  width,  and  clinical  stability.Sinus  bradycardia  in  the  neonate  always  requires  aggressive  evaluation  and  treatment.Infants  with  paroxysmal  supraventricular  tachycardia  (PSVT)  may  present  in  a  low  output  state  with  irritability,  poor  feeding,  tachypnea,  and  diaphoresis.The  presence  of  an  accessory  pathway  is  the  most  common  mechanism  for  PSVT  in  the  child,  but  is  difficult  to  appreciate  during  PSVT.  Digoxin  may  precipitate  ventricular  tachycardia  (VT)  and  is  only  used  under  the  supervision  of  a  pediatric  cardiologist.Atrial  fibrillation  or  flutter  associated  with  accessory  pathway  disease  or  hypertrophic  cardiomyopathy  (HC)  puts  a  child  at  high  risk  for  1:1  conduction,  ventricular  tachycardia,  and  sudden  death.
