DirectionalIncidence and Prevalence Interpretation
Sudden cardiac arrest, with its chilling math—averaging a fresh victim every two minutes in the US alone and claiming nearly all of them before a hospital can even try—stands as a grim, democratic tax on human mortality that the vast majority of us are woefully unprepared to pay.
