Key result
Frequency variation of ventricular fibrillation may serve as a useful parameter to predict first-shock defibrillation success in a rat model of cardiac arrest (P=0.005).
Why the study?
To evaluate whether the frequency variation of ventricular fibrillation helps predict successful defibrillation in a rat model of cardiac arrest.
Does the frequency variation of ventricular fibrillation predict successful defibrillation in a rat model of cardiac arrest?
Does the frequency variation of ventricular fibrillation predict successful defibrillation in a rat model of cardiac arrest?
In a rat model of cardiac arrest, the frequency variation of ventricular fibrillation may serve as a useful parameter to predict the success of the first defibrillation shock.

Should not change clinical defibrillation practice; leaves open translation of VF frequency variation beyond rat models.
BACKGROUND: To evaluate whether the frequency variation of ventricular fibrillation (VF) helps to predict successful defibrillation in a rat model of cardiac arrest. METHODS: VF was induced in rats followed by cardiopulmonary resuscitation and then defibrillation. The electrocardiographic signals of 30 rats with first-shock success were obtained from our previous animal experiments, and 300 rats without first-shock success were selected as control. The VF waveform immediately before the first defibrillation was analyzed. CONCLUSIONS: The frequency variation of VF may serve a useful parameter to predict defibrillation success.

Chen et al. (2019) studied Cardiac arrest with ventricular fibrillation (n=330). Frequency variation of ventricular fibrillation was evaluated on First-shock defibrillation success (p=0.005). Frequency variation of ventricular fibrillation may serve as a useful parameter to predict first-shock defibrillation success in a rat model of cardiac arrest (P=0.005).
