Early premature beats may heighten VF risk in asymmetric tissue; hypothesis-generating for mechanisms, leaves open human translation.
How does the prematurity of ventricular responses affect the fibrillation threshold?
Early premature ventricular beats have a significantly lower fibrillation threshold, which is inversely related to the asymmetry of the excitable field.
Han et al. (1966) studied this question.
