Abstract

Heart rate variability (HRV) is a fundamental physiological marker for assessing the autonomic nervous system’s (ANS) reaction. The response of the ANS is influenced by a variety of physical activities, i.e. body postural change. This paper aims to analyze the effect of physical activities such as postural change on HRV. To study this, a dataset of 56 subjects electrocardiogram (ECG) was self-recorded in two body postures (i) Supine and (ii) Standing. For the acquisition of ECG, the BIOPAC[Formula: see text]MP36 system has been used at a 500[Formula: see text]Hz sampling frequency. Further, HRV signals of each subject from recorded ECG have been extracted and selected linear, and nonlinear techniques have been used to determine the effect of postural shift on it. Further, the spearman rank correlation coefficient has been evaluated between the calculated parameters to determine the correlation between linear and nonlinear parameters. The obtained results indicate that the HRV is at a higher scale in the supine posture, while it is at a lower scale when the posture has been changed from supine to standing. The change that occurred in the response of HRV with the postural change indicates that the sympathetic activation of ANS is increased in the standing body posture.

用信号处理方法分析青壮年体位变化的HRV

心率变异性(HRV)是评估自主神经系统(ANS)反应的基本生理指标。ANS的反应受到各种身体活动的影响，即身体姿势的变化。本文旨在分析体位变化等体育活动对HRV的影响。为了研究这一点，56名受试者在两种身体姿势(i)仰卧和(ii)站立时的心电图(ECG)数据集被自我记录。对于心电的采集，采用了BIOPAC MP36系统，采样频率为500 Hz。此外，从记录的心电图中提取每个受试者的HRV信号并选择线性，并使用非线性技术确定姿势移位对其的影响。进一步，在计算参数之间评估spearman秩相关系数，以确定线性和非线性参数之间的相关性。结果表明，仰卧位时HRV处于较高的尺度，而由仰卧位变为站立位时HRV处于较低的尺度。HRV反应随体位变化的变化表明，站立体位时，ANS的交感神经激活增加。

期刊介绍： Biomedical Engineering: Applications, Basis and Communications is an international, interdisciplinary journal aiming at publishing up-to-date contributions on original clinical and basic research in the biomedical engineering. Research of biomedical engineering has grown tremendously in the past few decades. Meanwhile, several outstanding journals in the field have emerged, with different emphases and objectives. We hope this journal will serve as a new forum for both scientists and clinicians to share their ideas and the results of their studies. Biomedical Engineering: Applications, Basis and Communications explores all facets of biomedical engineering, with emphasis on both the clinical and scientific aspects of the study. It covers the fields of bioelectronics, biomaterials, biomechanics, bioinformatics, nano-biological sciences and clinical engineering. The journal fulfils this aim by publishing regular research / clinical articles, short communications, technical notes and review papers. Papers from both basic research and clinical investigations will be considered.
