Supports gastric distention increasing VF risk in canine pacing model; leaves open relevance to human arrhythmias.
Does acute gastric distention increase the tendency for ventricular fibrillation in dogs?
In a canine model, acute gastric distention significantly increases the vulnerability to ventricular fibrillation during accelerated pacing.
Miller et al. (2000) studied this question.
