ST- segment elevation on electrocardiogram in conditions other than acute coronary syndrome.
Pak J Med Health Sci Jan ;5(4):757-60.

Objective: Classify conditions leading to ST segment elevation on electrocardiogram in conditions other than acute myocardial infarction. Design: Cross-sectional descriptive study. Setting: Emergency Department of Medicine, Jinnah Hospital, Lahore. Duration: 6 months from 1-5-2006 to 31-10-2006. Patients and Methods: Total 100 patients were included. Brief history and clinical examination was performed in emergency ward. Twelve lead electrocardiogram was recorded at a paper speed of 25 mm/s and on amplification of 10mm/mv. It was interpreted by emergency doctor. Cardiac enzyme CK-MB was done in emergency ward to exclude acute myocardial infarction. Result: Among 100 patients 57 were male and 43 female. Mean age was 51.9±17.0. ST-segment elevation was recorded in 39 patients of left ventricular hypertrophy, 35 left bundle branch block, 20 benign early repolarization, 2 pericarditis, 1 right bundle branch block, 1 left ventricular aneurysm, 1 cerebrovascular accident and 1 hyperkalemia. Conclusion: It was concluded that left ventricular hypertrophy, left bundle branch block and benign early repolarization are the most frequent causes of ST-segment elevation in addition to acute myocardial infarction.
