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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …
