| Abstract | This study developed an automatic heartbeat classification system based on the morphological features extracted using the first-order linear prediction model with two optimal filter coefficients and the RR interval features normalized by the heart rate of individual patient to reduce the effects of inconsistent heart rates among patients. Three heartbeat classes, normal beats, supraventricular ectopic beats and ventricular ectopic beats obtained from the MIT-BIH Arrhythmia Database, were used to test the performance of the proposed method. The ECG data were divided into training and testing datasets, each containing about 50,000 heartbeats. The training dataset was first used to establish the optimal linear discriminant classifier, and then the testing dataset was applied to evaluate the classification performance. The study results demonstrate that the sensitivity and positive predictive value of the proposed method were 88.7% and 99.4% for normal beats, 79.5% and 30.1% for supraventricular ectopic beats, and 88.6% and 57.7% for ventricular ectopic beats, respectively. If the RR interval features without normalization were used, the sensitivity and positive predictive value for supraventricular ectopic beats decreased to 62.5% and 24.0%, respectively. |

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.
