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 …

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 …

Repolarization is where the cell goes back to its negatively charged state on the inside (hence it repolarizes). Therefore, this leads the heart muscle cell to relax.

Feb 4, 2025 · 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 …

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 …

Oct 8, 2024 · Benign early repolarisation (BER) is a usually benign ECG pattern producing widespread ST segment elevation that is commonly seen in young, healthy patients < 50 …
