Despite 40 years of cardiopulmonary resuscitation (CPR) therapies, overall
survival rates after cardiac arrest remain poor. Recent data suggest that
the death toll in the United States is greater than previously believed—possibly
450 000 sudden deaths each year—yet the average survival rate remains
lower than 5%.1 In contrast, the article by
Cobb et al2 in this issue of THE JOURNAL suggests
a lower incidence rate, about 184 000 cardiac arrests per year, as well
as a decreasing proportion of cardiac arrests with ventricular fibrillation
(VF) as the first identified rhythm.
