The probability of ventricular fibrillation (VF) relative to the peak left ventricular (LV) pressure and LV pressure over time (dP/dt) in 8-12 kg swine undergoing 48 km/h (30 mph) chest wall impacts with a baseball. The data exhibit a Gaussian distribution (p < 0.0001 by logistic regression). The highest incidence of VF was evident with peak LV pressures between 250 and 450 mmHg.
