My wife experienced SIPE at IM Hawaii2010, no wetsuit swim BTW>>>>She was able to continue with the bike and her shortness of breath continued to the point she had to walk and then eventually was coughing up aveolar fluid. DNF, trip to the med tent, pulse ox low 90’s, chest xray was complete whiteout. She has since been able to compete as a top national AG athlete and excel despite this single episode.SIPE is not a cause of acute deaths in a triathlon…and if it is it is very very rare, these deaths are all likely cardiac in nature…
