Original article Epidemiology and Pattern of Fascicular Block Following ST-Elevated Acute Myocardial Infarction

Aim: The aim of the study was to observe the epidemiology and pattern of fascicular block following ST elevated acute myocardial infarction (AMI). Background: Fascicular block following S-T elevated acute myocardial infarction is often seen in CCU. It predicts poorer in-hospital outcome and signifies underlying extensive myocardial damage with jeopardized conducting system. Materials and Method: This one year prospective observational study was carried out among the S-T elevated AMI patients in the CCU of NICVD during the period of January 2004 to December 2004. Hundred consecutive patients of first attack of AMI with or without fascicular block were included in this study. The patients suffering from congenital heart disease, cardiomyopathy, valvular heart disease and the patients having permanent pacemaker or preexisting syndrome were excluded from the study. Case selection was done with the help of history, physical examination, twelve leads surface ECG and echocardiography. Results: The mean age of the studied patients was 54.2±10.0 years. Highest percentage (38%) was in the age group 51-60 years. The mean age of male Patients was 51.0 ±9.9 years. Analysis reveals that the mean age of the female patients was significantly higher than the male patients. Among the studied patients, highest percentage had history of smokin
