Our preliminary research of heart rate variability (HRV) was carried out using BCG. BCG signal and electrocardiography (ECG) signal of 20 subjects were measured synchronously in static, valsalva maneuver, post valsalva maneuver and post exercise states. Cardiac periods of these two signals were calculated using RR intervals of ECG and JJ intervals of BCG respectively. HRV parameters in time domain analysis, in frequency domain analysis and nonlinear analysis were calculated. The correlation of HRV_BCG parameters and HRV_ECG parameters were checked; the significant differences between HRV_BCG and HRV_ECG parameters were tested using paired t-test. Results showed that the variance trends of cardiac periods calculated by ECG and BCG were the same; the correlations of HRV_BCG and HRV_ECG parameters were all above 0.81; HRV_BCG parameters showed no significant differences with HRV_ECG during static, post valsalva maneuver and post exercise state while nPNN50, LF/HF and SD₁ showed significant differences during Valsalva maneuver state., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=HCy9BAM+7ZzOEpFWE3JmRg==, pdfFileSize=1182496, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
