| Abstract | Impedance Plethysmographic (IP) observations from the arterial pulse forms a powerful tool for deciphering various cardiovascular diseases. However, a major bottleneck for applying this technique effectively is the assignment of variable waveform morphology to its respective diseases. Rationale of this work is to investigate Non linear and Dynamic Time Warping (DTW) approaches for classifying Impedance Plethysmographic (IP) waveforms. Our adaptation is two fold, firstly, where we establish the IP waveforms as a dynamic system using embedding dimension. Analysis of IP waveforms reveal the existence of eight different patterns corresponding to normal subjects and those suffering from diseases of heart, liver and lungs. Secondly we take up the task of classification of these patterns with template matching using DTW technique. Parametric evaluations reveal that IP waveforms exhibit dynamical nature in a three dimensional attractor. This observation is further validated by exhibition of determinism in reccurrence plots and by parameters determined using recurrence quantification analysis. Classification of the IP patterns by DTW on 1200 samples selected meticulously from 5628 patterns shows an average accuracy of 94%, 95% sensitivity, high statistical predictive values and kappa value of 0.9314 for the eight different classes. |

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.
