摘要:
[摘要] 心率减速力(deceleration capacity of heart rate,DC)检测是近年来发现的在动态心电图基础上所做的一项新的检测,是进行猝死高危人群筛选与预警的一项最新无创性心电技术,其能定量、独立地分析和测定迷走神经作用的强度,具有敏感性高、特异性强的特点。目前该技术在心血管疾病的应用上对判断自主神经受损程度、危险分层及在猝死高危人群的筛选与早期预警方面有较强的使用价值;在2型糖尿病的研究中发现糖尿病患者的DC值变化与血糖控制有关,但DC能否作为临床上诊断糖尿病心脏自主神经病变(diabetic cardiac autonomic neuropathy,DCAN)的新的参考指标尚有待进一步扩大样本研究证实。该文对DC检测的临床应用研究概况进行综述。

Abstract:
[Abstract] In recent years, the deceleration capacity of rate(DC) detection was found as a brand new detection which based on the dynamic electrocardiogram. It is also a latest noninvasive electrocardiograph technique which can screen and predict sudden-death for the population at high risk. The DC detection has the characters of high sensitivity and specificity and can quantitatively analyze the intensities of nervi vagus action. At present, it has application value in judging the degree of autonomic nerve damage, the risk stratification and the screening and early warning of sudden-death in high-risk patients in research of angiocardiopathy. The changes of DC have beeen found to be related to blood glucose control in the patient with diabetes mellitus, however whether DC can be a new reference index to diagnose diabetic cardiac autonomic neuropathy(DCAN)is debatable. The progress of clinical application research on deceleration capacity of rate detection is reviewed in this paper.
