  • cardiac voltage-gated sodium channels - conduction in the normal heart required for fast upstroke of the action potential
  • arrhythmogenesis
  • conduction disease

"Nav1.5 was observed to be heterogeneously expressed in the cardiac conduction system, with low abundance in the nodal tissues and high expression in the intraventricular conduction system. In addition, a transmural gradient across the ventricular wall exists, with low Nav1.5 labeling intensity and functional sodium channel availability in the subepicardium compared to subendocardium."
