小儿先天性心脏病术后心律失常诊治

Diagnosis and treatment of arrhythmias in children with congenital heart disease after surgery

先天性心脏病患儿发生心律失常，既与其心脏畸形有关，也可能是外科操作所致。抗心律失常治疗是基于快速和准确诊断。由于抗心律失常药物的负性肌力作用，药物治疗小儿心律失常时需权衡其利弊。近十年来，非药物治疗心律失常逐渐推广到儿科领域。

Arrhythmias in children with congenital heart disease may be associated either with the underlying abnormality or result from surgical intervention. The treatment rationale bases on the rapid and accurate diagnosis. As a general rule, risk-benefit analysis of drug therapy should be considered when facing an arrhythmia in a child, due to the negative inotropy. In the last decades, non-pharmacological therapy is progressively used in pediatric population.
