1. Hyperkalemia moves the resting potential closer to the normal threshold potential, thereby producing a more excitable state.

2. Resting potential; Action potential; Proton; Membrane potential.

3. Thus, the new concept was concluded that resting potential and action potential are membrane potentials of proton.

4. Several patch clamp configurations have been used to study the activity of ionic channels . The resting potential and capacitance as well as resistance of different lens cells were also measured.

5. Background— Cardiac repolarization, the process by which cardiomyocytes return to their resting potential after each beat, is a highly regulated process that is critical for heart rhythm stability.

6. Results Antiarrhythmic effect of COE may be related to its prolongation of action potential duration, increase of the absolute value of resting potential and a decrease of autonomy of sinus node.

7. Neither sodium valproate nor Verapamil showed any effect on action potential amplitude, overshoot, resting potential and phase O upstroke velocity.

8. And KATP channel played an important role in regulating resting potential associated with the tone of vascular smooth muscle cell (VSMC).
