  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. KCNJ8 - Wikipedia

    en.wikipedia.org/wiki/KCNJ8

    A mutation in KCNJ8 has been associated with cardiac arrest in the early repolarization syndrome. Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. K ir 6.1 is an integral membrane protein and inward-rectifier type potassium channel.

  4. Sudden arrhythmic death syndrome - Wikipedia

    en.wikipedia.org/wiki/Sudden_arrhythmic_death...

    Rare diseases called ion channelopathies may play a role such as long QT syndrome (LQTS), Brugada syndrome (BrS), CPVT (catecholaminergic polymorphic ventricular tachycardia), progressive cardiac conduction defect (PCCD), early repolarization syndrome, mixed sodium channel disease, and short QT syndrome. [13]

    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.

  6. 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%.

  7. 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.

  9. KvLQT1 - Wikipedia

    en.wikipedia.org/wiki/KvLQT1

    It's mutation causes Long QT syndrome, K v 7.1 is a voltage and lipid-gated potassium channel present in the cell membranes of cardiac tissue and in inner ear neurons among other tissues. In the cardiac cells , K v 7.1 mediates the I Ks (or slow delayed rectifying K + ) current that contributes to the repolarization of the cell, terminating the ...
