May not require total myocardial depolarization for defibrillation in canines; leaves open translation to human catheter use.
Does catheter defibrillation require total depolarization of the entire myocardium in a canine model?
Catheter defibrillation may not require simultaneous depolarization of the entire myocardium, as evidenced by distinct ECG patterns during the procedure.
Mower et al. (1974) studied this question.
