10 Possible Causes for Early Repolarization, Electrocardiogram Change, Myoclonic Jerking

  • Cocaine Abuse

    Effects of cocaine abuse on the oral mucosa are still poorly defined. Herein, a case of an 18-year-old male patient with a 15-day history of persistent painful ulcers and aphthous lesions of unknown etiology and with no other remarkable manifestations, is presented. All of the laboratory tests performed showed to[…][ncbi.nlm.nih.gov]

  • Sick Sinus Syndrome

    The change in the frequency of PAF from the observation period in the losartan and control groups was similar (-35 25 vs. -67 62 times; NS).[ncbi.nlm.nih.gov] Syncope may be accompanied by myoclonic jerks (convulsive syncope), but postictal confusion is absent.[ncbi.nlm.nih.gov] The simultaneous occurrence of V596M and R16472H may increase the severity of early repolarization.[ncbi.nlm.nih.gov]

  • Torsades De Pointes

    These include myocardial injury, electrocardiogram (ECG) changes and stress induced cardiomyopathy.[n.neurology.org] The following day, nursing staff observed repetitive, short-lived episodes of generalized mild myoclonic jerks. The patient remained conscious during these episodes.[consultant360.com] Therefore, in this context long or short QT syndrome, Brugada syndrome or early repolarization syndrome were unlikely. 6 Analysis of periods of torsade de pointes in our patient[revportcardiol.org]

  • Syncope

European Journal of Clinical Pharmacology, 60, 541 – 545.[apt.rcpsych.org] The following points need to be considered: Prompt recognition and diagnosis (brief seizure-like activity or involuntary myoclonic jerks have been reported in approximately[cry.ie] Patients having major clinical events showed more frequent Brugada type patterns, early repolarization, and more diffuse multivessel coronary vasospasms.[ncbi.nlm.nih.gov]

  • Carotid Sinus Syncope

    An electrocardiogram showed a regular rhythm consistent with sinus bradycardia (45bpm).[scielo.mec.pt] Patients in whom the cardiac arrest had lasted 14 seconds had 1 or 2 generalized myoclonic jerks.[ajnr.org] In patients with syncope, the clinical significance of the early repolarization pattern is unknown.

  • SHORT Syndrome

    And an electrocardiogram (ECG) may show abnormalities similar to those found in some heart attacks — in particular, changes known as ST-segment elevation.[health.harvard.edu] Myoclonic seizures (brief shock-like jerks of a muscle or group of muscles) appear between 1 and 5 years in 85% of children with Dravet syndrome.[epilepsy.com] High prevalence of early repolarization in short QT syndrome. Heart Rhythm 2010;7:647-52.[acc.org]

  • Familial Progressive Cardiac Conduction Defect Type 2

    Brugada syndrome Other names Sudden unexplained nocturnal death syndrome, bangungut, pokkuri death syndrome [1] (A) Normal electrocardiogram of the precordial leads V 1-3,[en.wikipedia.org] Seizures began at 21/2 years with arm stiffness, then clusters of right-sided facial twitching and weakness, then staring spells, eye twitching, and myoclonic jerks.[bcmj.org] Long-term outcome associated with early repolarization on electrocardiography. N Engl J Med 2009; 361: 2529–37.[aerjournal.com]
