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...

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...

متن کاملCocaine induced prolongation of the QT interval.
P rolongation of the QT interval is a serious electrocardiogram finding because of its association with torsades de pointes and sudden cardiac death. Both congenital and acquired factors can lead to abnormal lengthening of the QT interval. Six types of congenital long QT syndrome (LQT1– LQT6) have been described, each involving mutations in genes encoding potassium or sodium transmembrane chann...
