N2  - A rapid electrocardiographic technique, using a semireclining chair fitted with copper skin electrodes for arms and legs, has been employed in a screening survey of athletes during the routine preseason physical examinations. Mutually perpendicular leads I and aVF were recorded on 1,219 candidates. Following standards set by Dawber and Katz, 1,158 were normal, 51 doubtful, and 10 abnormal. Based on current knowledge, Wolff-Parkinson-White syndrome without history of paroxysmal arrhythmia is acceptable for strenuous sports; acquired bundle-branch block, right or left, should be suspected and thoroughly investigated; nodal rhythm and other second-degree block aggravated by exercise is cause for rejection as is myocardial ischemia and active myocarditis but not isolated T-wave changes. Cardiac contusion should be suspected in injuries of the anterior portion of the chest, and the patient should be permitted to play only when fully recovered.
