Repolarization - Wikipedia
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 …
Depolarization vs. Repolarization of the Heart (2024)
2024年10月18日 · Depolarization and repolarization are essential processes that maintain the heart’s electrical activity, ensuring the coordinated contractions necessary for efficient blood …
Does early repolarization on ECG increase the risk of cardiac …
2019年3月1日 · The early repolarization pattern is nearly always a benign incidental finding on ECG, with no specific signs or symptoms attributed to it. High-risk features on ECG are …
Physiology, Cardiac Repolarization Dispersion and Reserve
2023年4月17日 · A shared characteristic common to both cell types is the third phase, designated as repolarization. Repolarization defines the resetting of the electrochemical gradients of the …
Depolarization vs Repolarization of Heart Action Potential Explained
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.
Early Repolarization - Cedars-Sinai
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 …
Action potential: Definition, Steps, Phases | Kenhub
2023年11月3日 · An action potential is caused by either threshold or suprathreshold stimuli upon a neuron. It consists of three phases: depolarization, overshoot, and repolarization. An action …
Early repolarization - UpToDate
2022年5月16日 · The term early repolarization (ER), also known as "J waves" or "J-point elevation," has long been used to characterize a QRS-T variant on the electrocardiogram …
Early repolarization syndrome: A cause of sudden cardiac death
Early repolarization syndrome (ERS), demonstrated as J-point elevation on an electrocardiograph, was formerly thought to be a benign entity, but the recent studies have demonstrated that it …
Cardiac Repolarization in Health and Disease - ScienceDirect
