Key result
Break activation within the virtual electrode mechanism appears responsible for both the induction and termination of ventricular fibrillation during programmed stimulation.
The study demonstrates that 'break activation' in virtual electrode mechanisms is responsible for both the onset and cessation of ventricular fibrillation during programmed stimulation.
The authors used high-resolution optical recording technique to study the mechanism of protective zone during electrical induction of ventricular fibrillation (VF). Using programmed-stimulation, VF can be induced and terminated with successive stimuli. "Break activation" in virtual electrode mechanism appeared to be responsible for both the onset and cessation of VF.
