神经介导性晕厥儿童心室晚电位变化

The changes of ventricular late potentials in patients with neuraUy mediated syncope

神经介导性晕厥儿童存在自主神经功能紊乱，心室晚电位是预测恶性心律失常发生的指标，与自主神经功能密切相关，了解心室晚电位变化对临床预测神经介导性晕厥儿童的心血管事件具有一定价值。

Neurally mediated syncope children have autonomic nervous system dysfunction. Ventricular late potentials is closely related to the autonomic nerve function and is an index for predicting the occurrence of malignant arrhythmia. Understanding the changes of ventricular late potentials have a certain value in predicting cardiovascular disease of neurally mediated syncope children.
