Abstract
Electrocardiogram findings for the healthy 200 medical volunteers of age 20s who applied clinical trials for medical drugs in our clinic were analyzed following by their Minnesota cords. Only 16% of them were found to have no abnormal findings. Incidences of abnormal findings of infarct, axil deviation, myocardial ischemia, myocardial damages, atrioventricular conduction disturbance, bundle branch block, extrasystole, sinus arrhythmia, other pulsus irregularis, rotation and abnormal ST or T were 5.5, 12, 18.5, 3, 1, 6, 1, 2, 8.5, 17, 5.5 and 25.5%, respectively. These incidences were far higher than those for individuals who received health examinations in human dry dock. This fact suggested that many of these abnormal findings were caused not as organic changes as their diagnosis but as physiological changes followed by the active physical exercises during young ages.
