Electrocardiographic changes with special reference to coronary heart disease and physical activity at work among Egyptian employees

ABSTRACT

The study comprised 1121 workers with different levels of physical activity at work from a factory in Alexandria. The examined population was classified according to age, sex, occupation, level of physical activity at work and working duration. The examination included body weight and height, smoking habit, blood pressure, fasting blood sugar and an E.C.G. was recorded for each one. Studied population was categorized in groups according to the level of physical activity at work to four main groups i.e. heavy, moderate, sedentary [executive and intellectual] and drivers. Comparison between various occupational groups with different levels of physical activity at work in our study, revealed that a high significant frequency of ischaemic heart diseases associates sedentary life. After elimination of other significant factorials [age, obesity, D.M. and hypertension] that played a role in coronary heart diseases development among our sample, there is still frequent occurence of such disease among sedentary workers
