| Abstract | This paper describes a novel algorithm for real-time heartbeat classification based on the least square acceleration filter (LSAF) and the linear discriminant function (LDF). QRS complex was detected by LSAF with 30th order and the features were extracted. The performance of the proposed algorithm was evaluated using the MIT-BIH Arrhythmia database. The results showed the detection rate of 99% of the QRS complex and classification rate of 97% of various heartbeats such as normal beat, premature ventricular contraction, atrial premature contraction, left bundle branch block beat, and right bundle branch block beat. The algorithm was implemented on DSP chip in real time. We also compared the performance of the floating point simulation with that of fixed point simulation. There was no difference in the performance of the classification between the floating and fixed point simulation. But the computational cost of fixed point simulation was remarkably reduced than that of floating point simulation. It showed the possibilities that the proposed algorithm can be used effectively in the ambulatory monitoring. |

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.
