Why the study?

Does the amplitude of ventricular fibrillation predict survival after cardiac arrest?

Population

394 patients with cardiac arrest found initially in ventricular fibrillation

Comparison

Fine ventricular fibrillation (amplitude ≤0.2 mV) vs Higher amplitude ventricular fibrillation

Design

Cohort

Overview

Fine VF signals dismal prognosis in cardiac arrest; supports amplitude as prognostic marker but leaves open any therapeutic role.

Structured PICO

Does the amplitude of ventricular fibrillation predict survival after cardiac arrest?

P
Population
394 patients with cardiac arrest found initially in ventricular fibrillation
I
Intervention
Fine ventricular fibrillation (amplitude ≤0.2 mV)
C
Comparator
Higher amplitude ventricular fibrillation (>0.2 mV)
O
Outcome
Survival after cardiac arresthard clinical

Fine ventricular fibrillation amplitude (≤0.2 mV) is associated with delayed treatment initiation and serves as a powerful indicator of poor survival after cardiac arrest.
