Jonathan Dresner on sudden cardiac arrest among athletes: most common source sports #CCPRFSummit2021 
UW offers free online modules to educate clinicians on performing ECG screening for athletes uwsportscardiology.org/e-academy/ecg-…

Bike-mounted CPR/AED providers in Tokyo marathons: 100% survival from SCA among athletes possible if there is very rapid response. (I’m reminded here of John Hinds and his motorcycle work.)
Immediate post-arrest timeline
Basically normal breathing immediately after arrest is typical. This should NOT be considered a sign of a pulse. Current resuscitation guidelines to look for “normal breathing” do not apply in these witnessed athlete arrests.
Assume ALL SUDDEN COLLAPSE IN AN ATHLETE IS CARDIAC ARREST (until proven otherwise - but true sudden collapse usually is)! Forget seizure, syncope, etc.
Risk is higher among African Americans. Assumed to relate to genetic reasons, but much of the difference can be more directly linked to locale of upbringing - ie may be more due to socioeconomics than intrinsic medical causes.
Mortality is far higher at sporting events occurring outside of schools, presumably due to poorer readiness to provide CPR/AED
