| Abstract | One of the biggest single cause of mortality in the world is cardiovascular disease (CVD) and hence it is recognized that an early detection of its onset is vital for effective preventive therapies. Aortic stiffness has been shown to be an independent predictor of CVD, but its measurement is complex and time consuming. An alternative much simpler way of doing it is by looking for arterial properties such as arterial stiffness. This paper presents methods of estimating arterial parameters from measured ECG and PPG signals. PPG signal can be acquired easily by measuring the transmission of infra-red light through the finger tip. Two methods of obtaining arterial parameters have been used, one using simultaneously acquired ECG and PPG signals and another using PPG signal only. Pulse wave velocity, which is an indicator of arterial stiffness, has been measured using pulse wave transmit time derived from simultaneously recorded ECG and PPG signals. Arterial parameters like stiffness index, augmentation index etc have been derived from the PPG signals. These parameters have been obtained for subjects in two age groups and it is observed that the parameters show clear changes for the two age groups thus demonstrating their efficacy in detecting changes in the arteries with age. Power spectral analysis has been performed to show how frequency spectra are different for the two age groups. This study demonstrates the usefulness of ECG and PPG analysis in investigating the changes in the arterial characteristics of the vascular system with age; it has potential applications in healthcare. |

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.
