The EKGs are tricky because of who is qualified to interpret them and the differences between the different populations. For example, they can be normal in a lot of instances in younger populations just because some of the pathologies don't seem to appear until the 18 to 20 year old. So that's where it becomes tricky ... Adding the electrocardiograms to screening because it may be normal in a 12 or 14, or even 16 year old, and then as they get a little bit older it can turn abnormal and that's when we really worry about these pathologies popping up.
The other thing is, in looking at the EKGs, if you're not familiar with the electrocardiographic changes or the electrical changes in the heart and the structural changes of that happen with athletes, they can be looked at as abnormal when really these are normal physiologic changes or electric changes that happen in the heart, and that can lead to a lot of false positives or abnormal EKGs that look abnormal but they're really normal for that sort of athlete, and that can cause a lot of extra time lost in their athletics ... A lot of emotional issues just because they're out of their athletics. They're worried about heart disease and obviously the extra money it would take to go see a specialist or extra testing that may be normal.
