动态心电图检测在儿童晕厥诊断中的价值

Diagnostic values of Holter monitoring in children with unexplained syncope

动态心电图是儿童晕厥有价值的诊断工具，但不能作为筛查工具。推荐在初步评估后怀疑心源性晕厥和心电图异常的患儿中选择运用，对晕厥发作频繁的患儿有重要的诊断与鉴别诊断价值。如果有条件建议延长监测时间至48h。心率变异性的某些指标作为直立倾斜试验诊断自主神经介导性晕厥的预测指标可能具有参考价值。

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 he 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.
