Estimation of Left Ventricular Ejection Fraction From 12 Lead E.C.G – A Simple aid to Prediction of Prognosis in Myocardial Infarction.

Abstract

MATERIALS AND METHODS: All patients of acute myocarctial infarction, irrespective of age and sex, admitted in coronary care unit of Rawalpindi General Hospital, Rawalpindi during the period of 1st January, to 30th April, 1982, who fulfilled the criteria for selection, were included in the study. All the variables i.e. demographic, clinical, laboratory and Electrocardiographic, were interpreted and their mean with standard deviation was found. Group A & B was compared in relation to end points by X2 -method, and statistical significance determined [10). RESULTS: 40 patients fulfilled the criteria for selection and were included in the study. They were categorized into two groups i.e. group A or High risk group containing 27 patients and group B having 13 patients, on the basis of LVEF determined by ER and QRS scoring system. DISCUSSION: The literature regarding acute myocardial infarction is limited in Pakistan, especially its incidence in the general population (Urban and Rural) and its long term prognosis. All the physicians even at District or Tehsil level can use this method, and they should use it to differentiate patients into low risk and high risk groups, so that high risk patients can be treated energetically or referred to coronary care centres to minimize the mortality as well as morbidity in these poor risk patients.
