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 …

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.

Aug 10, 2025 · Repolarization allows the heart muscle to relax, enabling the chambers to refill with blood. This cycle of depolarization (contraction) and repolarization (relaxation) ensures efficient blood …

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 …

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 …

The meaning of REPOLARIZATION is restoration of the difference in charge between the inside and outside of the cell membrane following depolarization.

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 …

Jan 30, 2025 · In simple terms, repolarization is the process where a cell restores its resting state after being activated. This process is especially important in nerve and muscle cells, such as those in the …

Jun 14, 2025 · Repolarization is a critical phase in the cardiac action potential that enables the heart to reset and prepare for the next contraction. It is a complex process involving the coordinated effort of …
