Depolarization versus repolarization abnormality underlying inferolateral J-wave syndromes: New concepts in sudden cardiac death with apparently normal hearts.
1. Europace. 2016 Oct;18(10):1599-1607. Epub 2015 Dec 24. Slowed depolarization and irregular repolarization in catecholaminergic polymorphic ventricular tachycardia: a study from cellular Ca2+ transients and action potentials to clinical monophasic action potentials and electrocardiography.
Authors C Antzelevitch 1 , G X Yan, W Shimizu. Affiliation 1 Masonic Patients with ECG nonischemic ST segment elevation were prospectively studied to determine the accuracy of the initial ECG diagnoses. Evaluations were made of 131 consecutive patients by serial clinical, ECG, and echocardiography to establish a diagnosis. Eighty-six (66 percent) had an initial ECG interpretation of repolarization variant.
Other Comparisons: What's the difference? 2020-02-20 ECG BASICS & FUNDAMENTALS. Early repolarization (ER) is a common finding that can produce widespread ST segment elevation that may mimic STEMI or pericarditis. Convex and horizontal ST segment morphology is seen in STEMI and not early repolarization.

The more complicated answer involves a common misuse of the terms. Depolarization occurs when sodium channels open and Na+ ions enter the cell. The depolarization can drive the membrane potential as high as +50 mV, that is, close to the Nernst potential for Na. 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.

At one end of the neuron, there is a long cable called the axon, which ends in the synaptic buttons. Start studying polarization vs depolarization.

Se hela listan på ecglearning.com Depolarization is essential to the function of many cells, communication between cells, and the overall physiology of an organism. Action potential in a neuron, showing depolarization, in which the cell's internal charge becomes less negative (more positive), and repolarization, where the internal charge returns to a more negative value.
