Objective: To determine whether cardiac monitoring is required in chil
dren sustaining electric shock at Australian household voltage. Method
ology: Records of patients admitted via the Emergency Department of Pr
incess Margaret Hospital for Children, Perth, Australia, for the perio
d 1968-96 were retrospectively reviewed. The initial ECG findings of p
atients with an electric shock were recorded, and the development of a
ny arrhythmia. Results: Forty-four patients were identified, 40 of who
m had sustained a household electrical injury. One patient had an abno
rmal ECG on admission, none developed an arrhythmia and all survived.
Conclusions: Routine cardiac monitoring is not required after exposure
to Australian household electricity supply if the child is asymptomat
ic and has a normal ECG on presentation.
