| 摘 要: | 采用Pearson相关系数和组内相关系数(intraclass correlation coefficient,ICC)对20例正常志愿者短期和长期内心率变异性(heart rate variability,HRV)短时程频域参数的可重复性进行探讨。结果表明:HRV短时程频域各参数在短期和长期内都具有较好的可重复性,并且短期可重复性好于长期可重复性,为HRV用于临床检测和研究提供了基础依据。 |

| Abstract: | Pearson correlation coefficient and intraclass correlation coefficient (ICC) are used to study the short-term and long-term repeatability of the short-term frequency domain parameters of heart rate variability (HRV) with 20 healthy volunteers. The results show that the short-term frequency domain parameters of HRV have good short-term and long-term repeatability, and the short-term repeatability is better than the long-term repeatability, which provides a basis for HRV used in clinical testing and research. |
