Abstract | Exit sites of monomorphic ventricular tachycardia and focal sites of ventricular extrasystoles can be localized using an endocardial catheter in conjunction with a multichannel surface ECG, in order to find a suitable site for ablation. For this procedure, as well as for the diagnosis of these types of arrhythmia it is desirable to know the relation between surface ECG and site of origin accurately. This knowledge can be provided by endocardial pacing on well-known sites and recording the resulting ECG, but this method is hampered by the low resolution of catheter localization techniques, breathing of the patient, and cardiac motion. By pacing on an endocardial basket catheter, that has 64 electrodes, and simultaneously recording of the endocardial and body-surface leads, we may obtain useful data to establish the relation between pacing site, endocardial activation spreading, and surface ECG. These data can be used to create and verify localization methods for ectopic and paced beats. In this paper, we investigate the stability of basket-paced beats and localization results. |

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.
