摘要
通过 Holter 24h 心率变异性分析,对47例经 Holter 检出有不同程度心肌缺血的连续病例以及51例无冠心病证据的正常人组进行分析研究。结果表明:①Holter 检出有心肌缺血组与正常人组比较,时域法分析显示各参数标准差下降(P<0.05或 P<0.01):②频域法分析,Holter 检出心肌缺血组与正常人组比较,总能谱范围成份、低能谱范围成份及高能谱范围成份均明显减少(P<0.01)。提示 Holter 检出心肌缺血患者心率变鼻性较低,迷走神经对心脏的调节能力下降。
Holter was used for studing heart rate variability in 47 patients with myocardial ischemia assessed by ambula- tory electrocardiogram monitoring and 51 normal subjects.The results were as follows:①The myocardial ischemia group had low standard deviation assessed hy time domain analysis in comparison with normal subject group(P<0.05;P<0.01);②The myocardial ischemia group had a reduction of total-freqcuency power spectual componant,low-frequency power spectral component and high-frequency power spectral component assessed by frequency clomain analysis in comparison wiht normal subject group.It indicates the impariment of automatic nervous system is one of the characteristic of the patients with myocardial ischemia.
