雅达心达康干预对糖尿病自主神经病变患者心率变异性和胰岛素抵抗的影响 |
| 7. | Several questions in classical spectrum estimation are presented . at last the extrapolation of hrv signal is obtained . since the detected signal is
为了得到正确的谱估计，必须对有限长的信号外推得到无限长的信号。 |
| 8. | The measurement of cost of hrv mainly consists of five items to count the cost of obtainment , development , employment , maintenance and reassignment of hr
成本法所核算的项目主要有五项：取得成本、开发成本、使用成本、保障成本和离职成本。 |
| 9. | The vlf / hf by using ar presents trend of increasing , this is tallied with clinic . analyzing 5 minute hrv ( decubitus ) for 4 myocardial ifchemia sickness by using ar and fft
现代谱估计所得的vlf / hf比值随年龄( 20岁)增加基本呈现增加的趋势，与临床认识吻合。 |
| 10. | It is infered signal length is short , the spectrum resolving power is low by using fft method , so the vlf % and lf % by using 2 method has great difference
推测由于5分钟hrv信号点数较少， fft分析时分辨率不高，因此两种方法所得极低频vlf和低频lf有较大差异。 |
