心率变异性的临床应用价值

Clinical value of heart rate variability

心率变异性作为无创性评估心脏自主神经功能的指标,其应用范围包括心肌梗死、心律失常、心力衰竭、糖尿病并发症、非心血管系统疾病。心率变异性降低提示心血管疾病预后不良,有效应用这一指标有助于早期识别高危人群、减少心血管不良事件发生。该文综述了心率变异性的临床应用价值及其局限性。

Heart rate variability(HRV)serves as a non-invasive indictor for evaluating cardiac autonomic nervous function,and its scope of clinical applications includes myocardial infraction,arrhythmia,heart failure,diabetic complications,and noncardiovascular diseases.The reduced HRV is suggestive of the poor prognosis for cardiovascular diseases.This indicator can be helpful in early recognition of high-risk population and decrease of cardiovascular adverse events.This article reviews the clinical applications and limitations of HRV.
