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 …

Feb 4, 2025 · Repolarization occurs when potassium (K+) ions leave the cells, restoring the negative charge and allowing the heart muscle to relax. Note: Both processes rely on the movement of these …

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 …

When the electrical system of the heart does not operate as it is supposed to, early repolarization (ERP) can develop. ERP can be seen on an electrocardiogram (EKG). This painless procedure provides a …

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 …
