In the pacemaking cells of the heart (e.g., the sinoatrial node ), the pacemaker potential (also called the pacemaker current) is the slow, positive increase in voltage across the cell 's membrane (the membrane potential) that occurs between the end of one action potential and the beginning of the next action potential.

Heart Muscle Excitability - an overview ScienceDirect Topics

WebExcitability of a cardiac cell depends on the passive and active properties of the cell membrane. The passive properties include the membrane resistance and capacitance and the intercellular resistance. The most important determinant of reduced excitability is the reduced availability of Na + channels. WebPacemaker potential.
