| Abstract | Previous studies have proved that the heart rate variability (HRV) is preferentially expressed in cardiac diastolic period variability (DPV). Does that mean that DPV analysis should act as an alternative approach for characterizing the autonomic regulation? And do they behave in accordance with each other in all subjects with various ages? Our aim was thus to assess the age related changes in: 1) HRV and DPV through frequency domain analysis, and 2) the interactions between HRV and DPV in a nonlinear coupling analysis framework. Totally 60 healthy subjects were enrolled. Results showed that both LF and HF powers of DPV decreased with the increasing of age (both p<;0.001), which behaved generally in the same way with HRV. However, their coupling, especially in terms of short-range correlations (p<;0.01), decreased significantly with aging, which suggests that the interactions between HRV and DPV might provide additional valuable information for characterizing the autonomic regulation in aged individuals. |

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.
