| Abstract | Transcatheter ablation, a technology for electrically annihilating aberrant heart tissue, has been developed to cure certain forms of life-threatening cardiac arrhythmia. Originally entirely surgical procedures were used to remove the aberrant tissue but more recently three techniques have been developed for ablating cardiac tissues through electronically induced heating. These are: (1) the high energy DC-induced current method, (2) the radiofrequency (RF) energy method, and (3) the microwave probe radiator method. With all three techniques a flexible catheter probe is inserted, via a small incision made in an arm or leg, into the body through a vein and into the heart. The two former methods produce ablative heat through current flow from an electrode at the tip of the catheter to an electrode pad placed on the surface of the skin. The latter method produces heat exclusively through microwave radiation from the catheter probe. Presently the RF probe is most widely used because it avoids painful side-effects associated with high energy DC-induced current. As yet, only the high frequency radiator method has not been developed to the point that it can be used in humans. In the present paper some ofthe advantages, design challenges and research on the myocardial transcatheter microwave probe are discussed. |

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.
