Since the death rate rises to six fold for over age 50 and 10 fold over age 60, perhaps a separate waiver for male athletes (me included) that outlines the increased risk, the possible tests to check for increased risk (coronary artery calcium for Coronary Artery Disease along with a treadmill to maximum tolerated); the advisability of taking it easy in the swim, since studies show that going out at 80% in the swim results in overall improved time for all three disciplines, and maybe a video to listen to reviewing all of the data and suggestions for older triathletes in the swim. Having said that, it is unlikely that USAT would consider this.
I rather see certification you can complete the swim distance non stop.

I don’t disagree at all, but how do we know it’s high heart rate that is inducing these cardiac events. I know many seniors doing intense speed workouts on the track with no events. I wouldn’t mind seeing some controlled studies of the initial HR of open water swimmers going all out to see if it’s true. Even if it did occur there would need to be other issues to have the high HR correlate to a cardiac event. Some will point to underlying heart issues but even with the most generous data interpretations at least 50% of the cases the cardiac event was the first indication of any problem.
Perhaps we need to look deeper into the athlete's history for these cases. The heart does operate differently on a swim than the run. Could it be the group start? Could it be over reaching trying to catch someone way more fit to draft off of?
