Variable VF susceptibility in swine model; leaves open whether QRS/QTc variability predicts human commotio cordis risk.
What factors correlate with individual susceptibility to ventricular fibrillation triggered by chest wall impacts in a swine model?
Swine display a wide range of individual vulnerability to VF triggered by chest wall impact, suggesting mild abnormalities in cardiac depolarization and repolarization might underlie susceptibility to commotio cordis.
