Findings in canine models should not alter digitalis toxicity management; hypothesis-generating for human arrhythmia origins.
Does digitalis-induced ventricular tachycardia originate from the bundle branches or Purkinje fibers in dogs?
Digitalis-induced ventricular tachycardia in dogs originates primarily from the left bundle branch or Purkinje fibers.
Damato et al. (1971) studied this question.
