窦性心律震荡的临床研究进展

Current Research in Sinus Rhythm Shocks

窦性心律震荡是近几年提出来的心电学指标,它对心血管死亡危险的预测价值已被多项临床实验证实。窦性心律震荡主要反映了迷走神经(与交感神经平衡)的反射功能,迷走神经活性增加对心脏具有保护作用,而交感神经活性增强可提高心室室颤阈值,促使心律失常的发生,现就近年来国内外关于心律震荡现象在心血管中的临床应用研究进展做一简述。

Heart rate turbulence（HRT） has been proposed as an index for electrocardiology due to its reliability in predicting the hazard ratio for cardiovascular diseases in clinical experiments.HRT reflects the reflex function of the vagus nerve（in balance with the sympathetic nerve）.The activity increase of the vagus nerve have protective effect to heart.The activity increase of sympathetic nerve can obviously improve ventricle fibrillation threshold and cause the cardiac arrhythmia.This article reviews research from multiple countries on the clinical application of HRT.
