| Abstract | OBJECTIVE: The aim of this study was to investigate if the electrocardiographic (ECG) abnormalities assessed early in the emergency department (ED) are associated with the in-hospital mortality of the patients with spontaneous subarachnoid hemorrhage (SAH). METHODS: We studied prospectively a cohort of 222 adult patients with spontaneous SAH in an ED. A 12-lead ECG was performed for these patients in the ED. The patients were stratified into nonsurvivors and survivors based on the in-hospital mortality. The clinical characteristics, heart rate, corrected QT interval (QTc) and 7 predefined morphologic abnormalities were compared between these 2 groups of patients. RESULTS: Compared with the survivors (n=178), the nonsurvivors (n=44) had significantly slower heart rate (75±23 vs 83±16, P=.018) and more prolonged QTc (492±58 vs 458±40, P=.001). There were significantly higher frequency of occurrence of ECG morphologic abnormalities (66% vs 37%, P=.001) and nonspecific ST- or T-wave changes (NSSTTCs; 32% vs 12%, P=.015) in the nonsurvivors compared with those in the survivors. Multiple logistic regression model identified QTc (odds ratio, 1.0; 95% confidence interval, 1.0-1.0; P=.005) and NSSTTC (odds ratio, 3.3; 95% confidence interval, 1.0-10.7; P=.047) as the significant ECG variables associated with in-hospital mortality. CONCLUSIONS: The occurrence of NSSTTC and prolonged QTc assessed early in the ED are independently associated with the in-hospital mortality in adult patients with spontaneous SAH. |

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.
