Loss of regulation of the autonomic nervous system is found in many diseases from the age of 50 to 60 yr and even more so in older patients. The imbalance is usually manifested by an increase in sympathetic tone, long considered to be the most deleterious element in terms of cardiac rhythmic risk, but also by a reduction in the effectiveness of short-term regulation of the baroreflex arc (partial loss of parasympathetic control). Techniques for analysing this autonomic disorder by analysing heart rate regulation are widely available in outpatient clinics and provide interesting indicators of cardiovascular and cerebrovascular risk. Deceleration capacity of cardiac autonomic control has been identified for its prognostic role in high-risk patients and in the general population. Further research is indicated to assess the value of this marker in anaesthetic risk management by targeting procedures with greater risk of intraoperative and postoperative autonomic dysfunction.

心率减速能力作为围手术期风险的标志：识别相关的患者表型和手术程序


50 至 60 岁的许多疾病中都会发现自主神经系统失去调节，尤其是老年患者。这种不平衡通常表现为交感神经张力的增加，长期以来被认为是心律风险方面最有害的因素，但也表现为压力反射弧短期调节有效性的降低（副交感神经控制部分丧失） ）。通过分析心率调节来分析这种自主神经紊乱的技术在门诊诊所中广泛使用，并提供了心血管和脑血管风险的有趣指标。心脏自主控制的减速能力已被确定为高危患者和普通人群的预后作用。进一步的研究表明，通过针对术中和术后自主神经功能障碍风险较大的手术，评估该标志物在麻醉风险管理中的价值。
