| Abstract | AIM: Ventricular remodeling causes left ventricular hypertrophy (LVH) in myocardial infarction patients. We hypothesized that LVH can be evaluated using isointegral body surface maps. METHODS: Thirty-two patients with post-infarction stable chronic heart failure underwent a 64-electrode body surface mapping (isointegral QRS, QRST, ST and STT maps) and 2-D echocardiography. RESULTS: LVH was present in 16 of them (50%) according to 2D-echocardiography. Isointegral maxima increased and the minima were more negative in patients with LVH, and the differences were statistically significant for: isointegral QRS maxima (35±16 versus 60±21 mV.ms, p=0.0085) and minima (25±15 versus 69±14 mV.ms, p=0.0067), isointegral maxima and minima in the second third of the QRS complex, isointegral QRST minima and isointegral ST minima (5±2 versus 10±4 mV.ms, p=0.0026). Isointegral multipolar maps prevalence was increased in patients with LVH (75% versus 50%). Isointegral QRS and QRST maxima correlated best with the left ventricular mass (r=0.73 and 0.81). CONCLUSION: Body surface mapping is a useful method for the evaluation of patients with left ventricular hypertrophy in post-infarction heart failure. The most sensitive parameters are: isointegral QRS maxima and minima, especially in the second third of the QRS complex, isointegral QRST maps (minima, maxima and multipolarity) and isointegral ST minima. |

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.
