Animal data reinforce RPE mechanism at fibrillatory rates; leaves clinical translation open.
Does transcardiac shock induce refractory period extension at fibrillatory pacing rates in an animal model?
Transcardiac shocks induce refractory period extension even at fibrillatory activation rates, supporting RPE as a basic mechanism for defibrillation.
Gill et al. (1997) studied this question.
