Diagnostic values of Holter monitoring in children with unexplained syncope / 中华实用儿科临床杂志

ABSTRACT

Holter monitoring remains an useful diagnostic tool in the evaluation of syncope in children if synco-pe remains unexplained after the initial examination.But it should not be used as a screening tool.Holter monitoring is recommended in children who were suspected as cardiac syncope or who had an abnormal electrocardiogram.For chil-dren with frequent syncope,Holter monitoring is highly recommended.More information can be provided with extended Holter monitoring to 48 hours if possible.Heart rate variability is probably useful in predicting head -up tilt test diagno-sis of neurally mediated syncope.
