| Abstract | We study some dynamical measures applied to the study of electrocardiograms with two particular purposes. The first is the traditional need to determine the robustness of the measures with respect to limitations of the ECG such as a small number of data points, short sampling time and low sampling frequency. The second and more important purpose is to narrow the localization of the information captured by each measure in the particular case of ECGs. This may be an important contribution in order to be able to relate the information captured by a particular measure and aspects of the processes involved in the cardiac activity. With these purposes we have used a particular data base of electrocardiograms, ECG, constructed to study information that is not detectable by the expert visual analysis of the morphology of the ECG, nor by standard measures. This data base has been constructed by using carefully designed and controlled digital filters applied in small but critical ranges of the power spectrum of the ECG. |

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.
