The resting potential of the myocytes of the ventricle (phase 4) begins with the outside of the cell being positive—i.e., having a greater concentration of positive ions. Atrial and ventricular myocytes are normally quiescent (nonrhythmic); however, when the resting membrane potential is depolarized to a critical potential (Ecrit), a self-generating…
