13 Possible Causes for Early Repolarization, Myoclonic Jerking, Syncope

  • Cocaine Abuse

    A 48-year-old woman with a history of chronic intranasal cocaine abuse presented with unilateral proptosis associated with severe visual loss from optic neuropathy in the right eye. Imaging showed extensive bone and soft tissue destruction in the paranasal region and an orbital mass. Initial biopsies suggested a[…][ncbi.nlm.nih.gov]

  • Syncope

    jerking is common in syncope.[emed.ie] […] for syncope is identified.[ncbi.nlm.nih.gov] Why is ‘Benign’ early repolarization not a benign condition in patients with syncope? Which children with syncope should be admitted? and many more….[emergencymedicinecases.com]

  • Sick Sinus Syndrome

    Syncope may be accompanied by myoclonic jerks (convulsive syncope), but postictal confusion is absent.[ncbi.nlm.nih.gov] In this case report we describe an 80-year-old man with sick sinus syndrome (SSS) who developed syncope attacks.[ncbi.nlm.nih.gov] The simultaneous occurrence of V596M and R16472H may increase the severity of early repolarization.[ncbi.nlm.nih.gov]

  • Carotid Sinus Syncope

    Patients in whom the cardiac arrest had lasted 14 seconds had 1 or 2 generalized myoclonic jerks.[ajnr.org] Of the four types of treatment used in carotid sinus syncope, irradiation was ruled out because the patient had had irradiation before developing syncope, surgery was inappropriate[ncbi.nlm.nih.gov] In patients with syncope, the clinical significance of the early repolarization pattern is unknown. Recommendations for Early Repolarization Pattern 5.[ahajournals.org]

  • Torsades De Pointes

    The following day, nursing staff observed repetitive, short-lived episodes of generalized mild myoclonic jerks. The patient remained conscious during these episodes.[consultant360.com] BACKGROUND: A 43-year-old woman suffering from Steinert syndrome was admitted after experiencing multiple episodes of torsades de pointes-related syncope.[ncbi.nlm.nih.gov] 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]

  • Wilson Disease

    jerking similar to that seen in progressive myoclonic syndrome.[web.archive.org] A and B, Nonthoracotomy ICD system placed in a 39-year-old man with inoperable pulmonary atresia with ventricular septal defect who had ventricular tachycardia with syncope[dx.doi.org] […] lesions Abdominal imaging findings are neither sensitive nor specific Resting ECG abnormalities include left ventricular or biventricular hypertrophy, early repolarization[emedicine.com]

  • Sudden Cardiac Death

    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] Receiver-operating curve analysis evaluated the best parameter to identify patients with increased SCD risk 4% and patients with syncope or non-sustained VT.[ncbi.nlm.nih.gov] Patients having major clinical events showed more frequent Brugada type patterns, early repolarization, and more diffuse multivessel coronary vasospasms.[ncbi.nlm.nih.gov]

  • SHORT Syndrome

    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] Our patient was initially assessed in the ED with a clinical diagnosis of syncope.[revportcardiol.org] High prevalence of early repolarization in short QT syndrome. Heart Rhythm 2010;7:647-52.[acc.org]

  • Familial Progressive Cardiac Conduction Defect Type 2

    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] Guidelines for the diagnosis and management of syncope (version 2009).

N Engl J Med 2009; 361: 2529–37.[aerjournal.com]

  • Hypertrichotic Osteochondrodysplasia

    jerks.[genomeweb.com] It can result in palpitations, syncope, thromboembolic stroke, and congestive heart failure.[mybiosource.com] Examples of J-wave disorders are arrhythmias associated with an early repolarization pattern in the inferior or mid to lateral precordial leads, Brugada syndrome, some cases[genecards.org]
