The Transmural Activation Sequence in Porcine and Canine Left Ventricle Is Markedly Different During Long‐Duration Ventricular Fibrillation

Abstract

The transmural activation sequence in SR and LDVF is markedly different between pigs and dogs. These differences may be related to differences in Purkinje fiber and ion channel distributions and suggest that dogs are a better model for investigating activation sequences during LDVF, given the similarities with humans.
