We report a case of myocardial infarction\u2013related acquired long QT syndrome in a 58-year-old woman that had no clear cause and progressed to torsades de pointes requiring treatment with isoproterenol and magnesium. Despite negative results of DNA testing against a known panel of genetic mutations and polymorphisms associated with long QT syndrome, the patient's family history of fatal cardiac disease suggests a predisposing genetic component. This report serves to remind clinicians of this potentially fatal ventricular arrhythmia after myocardial infarction.<\/jats:p>","DOI":"10.14503\/thij-18-6872","type":"journal-article","created":{"date-parts":[[2020,6,30]],"date-time":"2020-06-30T19:59:46Z","timestamp":1593547186000},"page":"163-164","source":"Crossref","is-referenced-by-count":2,"title":["Acquired Long QT Syndrome after Acute Myocardial Infarction: A Rare but Potentially Fatal Entity"],"prefix":"10.14503","volume":"47","author":[{"given":"Samuel S.","family":"Gordon","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Hollowed","sequence":"additional","affiliation":[{"name":"Division of Cardiology, David Geffen School of Medicine at UCLA, Los Angeles, California 90025"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Justin","family":"Hayase","sequence":"additional","affiliation":[{"name":"Division of Cardiology, David Geffen School of Medicine at UCLA, Los Angeles, California 90025"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Macias","sequence":"additional","affiliation":[{"name":"Division of Cardiology, David Geffen School of Medicine at UCLA, Los Angeles, California 90025"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jessica","family":"Wang","sequence":"additional","affiliation":[{"name":"Division of Cardiology, David Geffen School of Medicine at UCLA, Los Angeles, California 90025"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Holly R.","family":"Middlekauff","sequence":"additional","affiliation":[{"name":"Division of Cardiology, David Geffen School of Medicine at UCLA, Los Angeles, California 90025"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"5628","reference":[{"issue":"4","key":"i1526-6702-47-2-163-b1","series-title":"Pacing Clin Electrophysiol","first-page":"414","article-title":"Acquired long QT syndrome and torsade de pointes","volume":"41","year":"2018","unstructured":"El-Sherif\n N,\n \n \n Turitto\n G,\n \n \n Boutjdir\n M.\n \n \n Acquired long QT syndrome and torsade de pointes.\n\t\t\t\t\tPacing Clin Electrophysiol2018;41(4):414\u201321."},{"issue":"7","key":"i1526-6702-47-2-163-b2","series-title":"Heart Rhythm","first-page":"1104","article-title":"Torsades de pointes following acute myocardial infarction: evidence for a deadly link with a common genetic variant","volume":"9","year":"2012","unstructured":"Crotti\n L,\n \n \n Hu\n D,\n \n \n Barajas-Martinez\n H,\n \n \n De Ferrari\n GM,\n \n \n Oliva\n A,\n \n \n Insolia\n R,\n \n \n et al.\n Torsades de pointes following acute myocardial infarction: evidence for a deadly link with a common genetic variant.\n\t\t\t\t\tHeart Rhythm2012;9(7):1104\u201312."},{"key":"i1526-6702-47-2-163-b3","series-title":"Eur Heart J","first-page":"85","article-title":"QT interval prolongation in acute myocardial infarction","volume":"6 Suppl D","year":"1985","unstructured":"Ahnve\n S.\n \n \n QT interval prolongation in acute myocardial infarction.\n\t\t\t\t\tEur Heart J1985;6 Suppl D:85\u201395."},{"issue":"4","key":"i1526-6702-47-2-163-b4","series-title":"J Am Coll Cardiol","first-page":"1168","article-title":"Pause-dependent torsade de pointes following acute myocardial infarction: a variant of the acquired long QT syndrome","volume":"38","year":"2001","unstructured":"Halkin\n A,\n \n \n Roth\n A,\n \n \n Lurie\n I,\n \n \n Fish\n R,\n \n \n Belhassen\n B,\n \n \n Viskin\n S.\n \n \n Pause-dependent torsade de pointes following acute myocardial infarction: a variant of the acquired long QT syndrome.\n\t\t\t\t\tJ Am Coll Cardiol2001;38(4):1168\u201374."},{"issue":"1","key":"i1526-6702-47-2-163-b5","series-title":"J Am Coll Cardiol","first-page":"259","article-title":"Clinical relevance of cardiac arrhythmias generated by afterdepolarizations.
