It's rare in young healthy-acting people. For example, http://www.sca-aware.org/sca-news/aha-releases-2015-heart-an... says that the incidence is 0.24 per 100k annually for high school athletes in Minnesota. Extrapolating that rate to the whole US population would give ~800 deaths per year. The observed 400k number includes quite a lot of people who suffer cardiac arrest after a history of heart disease. |
