  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]

  4. 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.

  5. 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.

  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. Long QT syndrome, Brugada syndrome, Andersen-Tawil syndrome, Early repolarization syndrome: Treatment: Avoidance of strenuous exercise, medication, implantable cardioverter defibrillator [2] Medication: Beta-adrenoceptor blockers, Verapamil, Flecainide [2] Prognosis: 13–20% life threatening arrhythmias over 7–8 years [3] Frequency: 1:10,000 [4]

    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.
