Multifactorial QT Interval Prolongation and Takotsubo Cardiomyopathy
Figure 2
(a) ECG on admission to community hospital demonstrating normal sinus rhythm and QT interval prolongation (QTc = 544 msec). (b) ECG two days following admission demonstrating marked T-wave inversion and QT prolongation (QTc = 634 msec). (c) ECG on discharge demonstrating improvement of T-wave inversion abnormalities and shortening of the QT interval (QTc = 514 msec). (d) and (e) Left ventriculography at end-diastole and end-systole, respectively. Note the apical ballooning characteristic of Takotsubo Cardiomyopathy.
