  2. Benign early repolarization - Wikipedia

    en.wikipedia.org/wiki/Benign_early_repolarization

    Research in the late 2000s has linked this finding to ventricular fibrillation, particularly in those who have fainted or have a family history of sudden cardiac death. [5] [6] [7] Although there is a significant relationship between ventricular fibrillation and some early repolarization's patterns, the overall lifetime occurrence of idiopathic ventricular fibrillation is exceptionally rare. [8]

  3. Repolarization - Wikipedia

    en.wikipedia.org/wiki/Repolarization

    A labeled diagram of an action potential.As seen above, repolarization takes place just after the peak of the action potential, when K + ions rush out of the cell.. 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.

  4. T wave - Wikipedia

    en.wikipedia.org/wiki/T_wave

    Repolarization of the ventricle happens in the opposite direction of depolarization and is negative current, signifying the relaxation of the cardiac muscle of the ventricles. But this negative flow causes a positive T wave; although the cell becomes more negatively charged, the net effect is in the positive direction, and the ECG reports this ...

  5. Subarachnoid hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Subarachnoid_hemorrhage

    J waves or Osborn waves, which represent an early repolarization and delayed depolarization of the heart ventricles, are thought to be caused by the high catecholamines surge released in patients with subarachnoid hemorrhage or brain damage, the issue that might lead to ventricular fibrillation and cardiac arrest in unmanaged patients. [39] [40]

    The clinician must therefore be well versed in recognizing the so-called ECG mimics of acute myocardial infarction, which include left ventricular hypertrophy, left bundle branch block, paced rhythm, early repolarization, pericarditis, hyperkalemia, and ventricular aneurysm.

  8. Acute pericarditis - Wikipedia

    en.wikipedia.org/wiki/Acute_pericarditis

    Early repolarization usually occurs in young males (age <40 years) and ECG changes are characterized by terminal R-S slurring, temporal stability of ST-deviations and J-height/ T-amplitude ratio in V5 and V6 of <25% as opposed to pericarditis where terminal R-S slurring is very uncommon and J-height/ T-amplitude ratio is ≥ 25%.
