The action potential of a myocyte is broken into five phases. Often they’re shown on a graph of membrane potential vs. time. We’re going to start at Phase 4, because why not. In phase 4, or the resting phase, our little myocyte friend is at rest, hanging out with an overall charge or membrane potential of -90 mV.

The action potential occurs in all cardiac cells but its appearance varies depending on cell type. During de- and repolarization ions (Na+ [sodium], K+ [potassium] and Ca2+ [calcium]) flows back and forth across the cell membrane. Because ions are electrically charged, their movement generates an electrical current.

When a cardiac myocyte becomes stimulated, the resting membrane potential (-90 mV) becomes more positive and an action potential is generated if the threshold (-70 mV) is met. The action potential will first “summit” as the voltage across the …
Action Potential in Cardiac Pacemaker Cells

The action potential in the SA node occurs in three phases which are discussed below. Phase 4 – Pacemaker potential The pacemaker potential occurs at the end of one action potential and just before the start of the next. It is the slow depolarisation of the pacemaker cells e.g. cells of the sinoatrial node, towards the membrane potential threshold.
The Action Potential in Ventricular Cells
https://teachmephysiology.com/cardiovascular-system/cardiac-cycle-2/action-potential-ventricular-cells/
Action potentials in ventricular myocytes trigger the Ca 2+ entry that is necessary for their contraction. Their synchronicity, characteristic shape and length protect the heart against abnormal electrical activity. When these protective mechanisms go …

Cardiac action potentials. There are two types of action potential (AP) in the heart. Slow/brief action potential that is created in the SA and AV nodes, and fast/long action potential that occurs in the atrial and ventricular myocytes and the specialized conducting fibers (Fig. 1B) [].A fast action potential has several phases.

The propagating cardiac action potential fulfils these roles. Figure 1 illustrates the 5 phases of the normal action potential: Phase 4, or the resting potential, is stable at ≈−90 mV in normal working myocardial cells. Phase 0 is the phase of rapid depolarization. The membrane potential shifts into positive voltage range.
