摘要
心血管系统的生理活动受自主神经系统调节,自主神经功能紊乱将导致多种疾病的发生发展。心率减速力(deceleration capacity of rate,DC)与连续心率减速力(heart rate decelera tion runs,DRs)测定操作简便、结果稳定可靠,是优良的自主功能监测手段。它们在心肌梗死、房颤、心脏瓣膜病中联合其他指标可显著改善危险分层效率及预后评估效果,为高危患者提前示警。此外,DC与心肌病、高血压、心力衰竭等心血管疾病也有一定的关联,但具体临床意义及价值仍有待进一步研究。DC与DRs检测是极具临床价值及发展潜力的心电监测手段,值得在临床中广泛使用及进一步研究扩展。
The autonomic nervous system regulates physiological activities of cardiovascular system,and dysfunction of autonomic nerve will result in the occurrence and development of many diseases. Testing of deceleration capacity of rate( DC) and heart rate deceleration runs( DRs) is easy and simple to handle,stable and reliable,which serves as an ideal method for monitoring autonomic function. With combination of the two indices and others,the efficiency of risk stratification and prognosis evaluation can be significantly improved in patients with myocardial infarction,atrial fibrillation,and heart valve disease,making early warning for high-risk group. Additionally,DC is also related to cardiovascular diseases including cardiomyopathy,hypertension,and heart failure,however,the specific clinical significance still needs further research. The electrocardiographic testing of DC and DRs proves to have great clinical value and development potential,which is worthy of being prevalent clinically and investigated further.
