| 中文摘要: |
| 目的：了解扩张型心肌病患者恶性心律失常(MVA)与心率变异性( heart rate variability，HRV) 的关系，探讨扩心病患者体内
自主神经变化的临床意义。方法：选择扩心病患者48例作为研究对象，同时按照年龄配对，取48例正常者作为对照组，对其行24
小时动态心电图检查，依据其是否出现恶性心律失常分为恶性室性心律失常(MVA+)组及单纯扩张型心肌病(MVA-)组，分析组间
HRV的差异。结果：与对照组比较，单纯扩张型心肌病(MVA-)组HRV时域指标(SDNN、SDANN、RMSSD)均有降低(P＜0.05)L 与
(MVA-)组相比，恶性室性心律失常(MVA+)组HRV相关指标进一步降低(P＜0.05)。结论：自主神经功能异常是扩张型心肌病患者
恶性心律失常的重要危险因子，可能可以用HRV预测其发生恶性心律失常危险性。 |
| 英文摘要: |
| Objective: To analyze the relation between Heart Rate Variability (HRV) and malignant ventricular arrhythmia(MVA)
in patient with dilated cardiomyopathy (DCM), and to provide clinic basis for predicting the risk of death. Methods: We divide the 48
patients with dilated cardiomyopathy into 2 groups according to MVA, we also collect 48 normal people as control. They are MVA(+)
group, MVA(-) group and normal control group. We analyze the difference of HRV indexes such as SDNN, SDANN and RMSSD among
the 3 groups. Results: The indexes of SDNN, SDANN and RMSSD in MVA (+) group are lower than those in MVA (-) group, and the
indexes of HRV in MVA (-) group is lower than normal group using ANOVA. Conclusions: MVA is closely related to the decrease of
HRV. HRV might be used to predict the incidence of MVA and sudden death in patient with DCM. |
