Don’t quote me on this; however, this is how I think the process goes:
I can’t recall if the general pre-screening/physicals include that assessment; however, diagnostic tests such as this are performed on an individual basis when information is passed on from the players trainers or physician back home or if a player is symptomatic of some type of cardiac issue here.
I believe MRI and ECG are the ones.
We are fortunate in that our sports medicine facility is about 300yds down the block from our training facility.
