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 …

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 …

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.

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.

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 …

Jan 1, 2023 · Here we discuss how research into the genetic and electrophysiological basis of repolarization has provided us with insights into cardiac repolarization in health and disease and how …

Aug 12, 2023 · Cardiac repolarization refers to the electrical phase of the cardiac cycle when the myocardium recovers its resting state following depolarization. Repolarization is a complex process …
