Adjudicated etiologies of resuscitated SCAs surviving to hospital admission after review of comprehensive hospitalization records (69.2%=cardiac arrhythmic, 27.1%=Noncardiac, 3%= Cardiac Non-arrhythmic. Non-Survivor. Adjudicated etiologies of resuscitated SCAs who died during initial inpatient hospitalization (55.8%= Cardiac-arrhythmic, 41.9%=Non-cardiac, 2.3%=Cardiac Non-arrhythmic). Survivor.Adjudicated etiologies of resuscitated SCAs who survived to hospital admission (91.5%= Cardiac-arrhythmic, 4.3%=Cardiac Non-arrhythmic, 2%=Non-cardiac). Bolded P-values are less than or equal to 0.05. CAD=Coronary Artery Disease, DKA=Diabetic Ketoacidosis, GI=gastrointestinal, SCA=Sudden Cardiac Arrest.
