| Abstract | Our aim was to compare the spectral measures of heart rate variability (HRV) with those of the variability of: impedance heart periods (IHPV), ejection time (ETV) and diastolic time (DTV), computed from the impedance cardiography (ICG) traces obtained from 17 healthy volunteers during four 5-min steady-state conditions that elicit different vagal activity levels. From the time-frequency spectra of RR intervals (RR), impedance heart period (IHP), IHP-RR difference, ejection time (ET) and diastolic time (DT) series, their corresponding high frequency $(HF_{RR},$ $HF_{IHP-RR})$ and low frequency powers $(LF_{RR},$ $LF_{IHP-RR})$ were computed. Time-frequency coherences of $HF_{RR}$ and $LF_{RR}$ with the respective components of the other series were obtained. Coherences and correlations of HRV spectral measures with those of IHPV and DTV were very strong and much greater (p<;0.01) than with those of ETV. $HF_{IHP-RR}$ power was much greater (p<;0.005) than $LF_{IHP-RR}$ in all maneuvers. Although HRV determines most IHPV, the latter contains additional respiratory modulation that limits their interchangeability. Intra-beat variability is documented by DTV, a surrogate of HRV and therefore susceptible to autonomic modulation, and by ETV, which is much reduced and less responsive to modulation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
