Favorable neurological outcome and survival rate at hospital discharge in initial cardiac rhythm. A The proportion of favorable neurological outcome at hospital discharge in initial rhythm at the scene of shockable rhythm, pulseless electrical activity (PEA), and asystole is 16.7%, 9.2%, and 3.9%, respectively. B The survival rate at hospital discharge in initial rhythm at the scene of shockable rhythm, PEA, and asystole is 32.0%, 18.5%, and 10.8%, respectively. A favorable outcome is defined as a cerebral performance category (CPC) of 1 or 2, whereas an unfavorable outcome is defined as a CPC of 3, 4, or 5. Data on initial cardiac rhythm at the scene were missing for 16 patients
