In neuroscience, repolarization refers to the change in membrane potential that returns it to a negative value just after the depolarization phase of an action potential which has changed the membrane potential to a positive value. The repolarization phase usually returns the membrane potential back to the resting membrane potential. The efflux of potassium (K ) ions results in the falling phas… WebEarly repolarization refers to ECG findings typically including J-point elevation ≥ 0.1 mV, often with a slurred or notched appearance, followed by ST-segment elevation in 2 or more contiguous leads. This ECG pattern is not uncommon, as it occurs in about 5% to 10% of the population, especially in men, younger patients, and athletes.

WebOne of the limitations of the study is the measurement of ventricular depolarization and repolarization times on the surface ECG, which may have led to less accurate values. Other techniques, such as noninvasive electrocardiographic mapping or invasive activation mapping, provide more accurate results but are more difficult to use intraoperatively. WebThe P wave represents the depolarization of the atria, the QRS complex represents the depolarization of the ventricles, and the T wave represents the repolarization of the ventricles.
