Repolarization is a stage of an action potential in which the cell experiences a decrease of voltage due to the efflux of potassium (K +) ions along its electrochemical gradient. This phase occurs after the …

Dec 11, 2024 · Depolarization and repolarization are essential parts of the heart’s cycle, affecting muscle contraction and relaxation. In simpler terms, depolarization is when the heart cells fire off an …

Jan 12, 2026 · Definition: Repolarization refers to the process where the heart cells return to their resting electrical state after depolarization. It restores the negative charge inside the cells.

Jul 23, 2025 · Following contraction, heart muscle cells reset for the next beat. This recovery phase is repolarization, where potassium ions flow out of the cells, restoring their resting electrical state. An …

Then right after the heart cell contracts it needs to relax. This is referred to as repolarization. Repolarization is where the cell goes back to its negatively charged state on the inside (hence it …

Repolarization is the process during which a cell's membrane potential returns to its resting state after depolarization, primarily involving the movement of ions across the cell membrane.

Repolarization refers to the phase of the cardiac cycle where the heart muscle cells recover their resting state after depolarization, which is reflected in the electrocardiogram (ECG) as changes in the ST …
