| Abstract | In order to evaluate the factor of cardiovascular risk in hypertensive patients, the most common measured physiological parameter is the arterial blood pressure (BP), often leaving out of considerations other important cardiovascular parameters, such as mechanical arterial compliance. To better evaluate the inherent variability of blood pressure, with respect to the control of cardiovascular system and situational determinants, a computerised system has been developed. By means of a PC, equipped with a 12 bits A/D board, BP, heart rate patient voice and posture and external temperature have been acquired. The systolic, diastolic, and mean values of BP and the heart rate have been continuously, beat-to-beat, acquired with a Finapres, while ad hoc developed sensors have been used to acquire the other parameters. The signals, acquired in the different detected situations, have been processed by means of a software developed in LabView environment. A linear regression of systolic blood pressure and RR interval in agreement with the Karemaker equation, is carried out, evaluating the baroceptorial system sensitivity. The developed system may be usefully exploited in the investigation of the baroceptorial reflex and the of control mechanism of cardiovascular system. Moreover, the multiparametric accomplished analysis method could be used in the evaluation and in the setting up of pharmacological interventions. |

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.
