Sudden cardiac death risk assessment and athletes health concerns are prerequisites for advancement in competitive sports. Preventive examinations promptly identify the risks that may be associated not only with heritage but also with psychophysical overload in sport. Sudden cardiac death is the most important cause of athlete health care. The risk factors which can lead to death are congenital and acquired diseases of the heart and blood vessels. Cardiovascular risk assessment is of great importance for the athlete himself and for all involved working with athletes. Changes in electrocardiogram findings are most commonly associated with morphological and functional changes related to »Sports Heart Syndrome«, i.e. heart adaptation to increased exercise load. Knowledge of the electrogardigraphic finding of an athlete is necessary because findings can often be similar to a finding of a sick heart which can result in unnecessary exclusion of an individual from sports and sports competitions, and thus impair the athlete's mental and emotional health and economic security, especially if the individual is a professional athlete. According to the guidelines of the European Cardiology Society, which has also been accepted by the Croatian Cardiology Society, electrocardiographic screening of athletes in European countries is the »Gold Standard«, unlike in American countries where electrocardiogram is not given much importance. Misinterpretation of electrocardiographic findings can lead to a high rate of false-positive findings and unnecessary cardiac diagnostic processing, which negatively affects the athlete and increases the health care of the athlete. An example of a solution to the correct interpretation of athletes' electrocardiographic findings are internationally recognized criteria such as Seattle Crtiri and SDS Module from 2013, which, by means of an automatically standardized high sensitivity test, select the athletes with normal electrocardiographic findings and those with abnormal findings requiring further diagnostic and cardiac processing. The purpose of electrocardiographic screening in the assessment of the risk of sudden cardiac death is to preserve the health of athletes, both while playing sports and after completing their sports careers.
