Quantitative analysis of the electrocardiogram among healthy adult Iraqi males.
12-lead electrocardiography was studied in 522 healthy Iraqi males selected randomly between the ages of 20-50 years. The measurements performed included intervals, amplitude and QRS axis. Their relations to body build and blood pressure were evaluated. The distribution mean value was studied and compared with similar data from Western populations. There is no change in QRS axis within the age groups studied. The R-and T-waves are significantly higher than corresponding waves from Western populations. Therefore, many of left ventricular hypertrophy patterns on voltage criteria could not be applied accurately. This study shows some difference in the electrocardiographic pattern of a Middle Eastern population which can be of value in the assessment of cardiovascular epidemiology.
