الوصف: Aim: Fatal arrhythmia is the main cause of sudden death in patients with acute myocardial infarction either during hospital admission or in post-discharge period. Our aim is to identify groups at high risk of arrhythmic mortality by using a simple bed-side test in electrocardiogram. Background: Trans-mural dispersion of repolarization (TDR) in patients with ST elevation myocardial infarction is the main trigger of arrhythmias. The potential value of measuring the interval between the peak and end of the T wave (Tpeak-Tend, Tp-Te) as an index of spatial dispersion of repolarization is a parameter thought to be capable of reflecting dispersion of repolarization and thus may be prognostic tool for detection of arrhythmic risk. Little is known about its use for identifying risk of arrhythmias in acute myocardial infarction and this must be approached with great caution and require careful validation. Methods: A prospective analysis of data from 564 patients admitted to our CCU by acute myocardial infarction along a period of two years from January 2012 to December 2013 was done. After exclusion of valvular, congenital lesions, HOCM, IDCM, pericardial diseases, accessory pathway, any Bundle branch block, metabolic disorders and re-perfusion arrhythmia. Analysis of TpTe interval and its dispersion were done for all patients and a Holter-24 h was performed after one month. Patients were then classified into two groups based on Lown grading score for arrhythmia: group (I) (441 patients) with no or minimal arrhythmias (Lown score
