Multifactorial QT Interval Prolongation and Takotsubo Cardiomyopathy
A 71-year-old woman collapsed while working as a grocery store cashier. CPR was performed and an AED revealed torsades de pointes (TdP). She was subsequently defibrillated resulting in restoration of sinus rhythm with a QTc interval of 544 msec. Further evaluation revealed a diagnosis of Takotsubo Cardiomyopathy (TCM) contributing to the development of a multifactorial acquired long QT syndrome...
متن کاملTakotsubo cardiomyopathy and QT interval prolongation: who are the patients at risk for torsades de pointes?
OBJECTIVES QT interval prolongation is prevalent among patients with Takotsubo cardiomyopathy (TC), whereas torsades de pointes (TdP) has rarely been reported in these patients. We studied all peer-reviewed reports on TC-associated QT interval prolongation and all peer-reviewed reports on TC-associated TdP to characterize the clinical circumstances leading to TdP in patients with TC. METHODS ...
متن کاملTorsades de Pointes in Takotsubo Cardiomyopathy with QT Prolongation
Takotsubo cardiomyopathy, or stress-induced cardiomyopathy, is characterized by reversible left ventricular apical ballooning associated with emotional or physiologic stress, mimicking acute myocardial infarction in the absence of significant coronary artery disease at angiography. Although the prognosis for patients with Takotsubo cardiomyopathy is relatively good, it is reported to be associa...
متن کاملDrug-Induced Prolongation of the QT Interval
N Engl J Med 2004;350:1013-22. Copyright © 2004 Massachusetts Medical Society. n the past decade, the single most common cause of the withdrawal or restriction of the use of drugs that have already been marketed has been the prolongation of the QT interval associated with polymorphic ventricular tachycardia, or torsade de pointes (Fig. 1), which can be fatal. 1 Nine structurally unrelated drugs...
متن کاملProlongation of the QT interval by ketanserin.
In hypertensive patients single doses of ketanserin 40 mg prolonged the corrected QT interval (QTc) for at least 8 hours, with a maximal increase of 35 ms (P less than 0.001, n = 6) after 2 hours. During chronic dosing (20 and 40 mg b.d.) the QTc was further prolonged, by 46 and 45 ms respectively. QTc prolongation after treatment with a mean dose of 73 mg/day for 7 weeks (n = 26) was significa...
