| Abstract | In this paper we propose a real-time method for discrimination of ventricular ectopic and normal beats in the electrocardiogram (ECG). The heartbeat waveforms were evaluated within a fixed-length window around the fiducial points (100 ms before, 100 ms after) after being normalized. Our algorithm was designed to operate with no expert assistance; the operator is not required to initially select any known beat templates which makes it applicable in real-time. It is based on the dominancy of normal beats during the first several seconds for most of records which mostly match the real cases. In addition to R-R intervals, we extract other features as beat width, P wave existence for each beat. Also we apply template matching between the learned template and the unknown beat where template beats are created for each beat shape on runtime. Template matching not only classifies normal dominant beat but also multi-form ventricular ectopic beats where each form is classified separately so as doctors and medical stuff could take the better decision. Our proposed algorithm was tested on MIT-BIH ECG database records with normal and ventricular ectopic beat classes defined in AAMI standard while other records are excluded. Our results show 97.24% overall accuracy with 98.93% and 94.54% sensitivities for normal and ventricular ectopic beats 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.
