“…[1][2][3] Indeed, sudden cardiovascular deaths in athletes are rare (albeit tragic) events, insufficient in number to be judged as a major public health problem or to justify a change in national healthcare policy. The most frequently cited obstacles to mandatory national screening of trained athletes are as follows: (1) the large number of athletes to be screened nationally on an annual basis (ie, ≈10-12 million); (2) the low incidence of events 1,8,10,11,18,[24][25][26] ; (3) the substantial number of expected falsenegative and false-positive results, in the range of 5% to 20% depending on the specific ECG criteria used [1][2][3][28][29][30][31][32] ; (4) cost-efficacy considerations, that is, the extensive resources and expenses required versus few events in absolute numbers; (5) liability issues that unavoidably impact physicians with the sole responsibility to disqualify athletes from competition and enforce that decision; (6) the lack of resources or physicians dedicated to performing examinations and interpreting ECGs, in contrast to the longstanding sports medicine program in Italy [4][5][6]9 ; (7) the influence of observer variability, technical considerations, and the impact of ethnicity/race on the interpretation of ECGs, which is particularly important for multicultural athlete populations such as in the United States; (8) the need for repetitive (ie, annual) ECG screening during adolescence, given the possibility of developing phenotypic evidence of cardiomyopathies during this time period or later 33 ; (9) the logistical challenges and costs related to second-tier confirmatory screening with imaging and other testing, should primary evaluations raise the suspicion of cardiac disease; and (10) recognition that even with testing, screening cannot be expected to identify all athletes with important cardiovascular abnormalities, and a significant false-negative rate may occur. 34 …”
