We have established that Force Lightning produces an electric current in the victim's body and produces the same effects as an electric shock. One of the possible effects of electric shock includes ventricular fibrillation, which results in loss of consciousness and death within a matter of minutes unless treatment is provided. Ventricular fibrillation can be triggered by a relatively low electric current (especially if the current passes through the heart), so even relatively weak Force Lightning could be lethal.
Has Force Lightning ever been depicted as causing ventricular fibrillation in a victim, either deliberately or accidentally? In other words, has a book ever described a Force Lightning attack as causing ventricular fibrillation or cardiac arrest, or has a visual depiction of a Force Lightning attack ever caused the victim to behave as someone with ventricular fibrillation? I am looking for examples from canon and/or Legends.
