Takotsubo T Waves---a Diagnostically Useful Electrocardiographic Pattern in 10 Case Presentations

We present 10 case presentations of takotsubo cardiomyopathy focusing on the electrocardiographic (ECG) findings. The consistent and diagnostic useful findings included diffuse, often exaggerated t-wave inversions as well as prolongation of the corrected QT interval. The t-wave changes have been associated with takotsubo cardiomyopathy with a specificity of more than 95% in some studies and are most supportive of this diagnosis in the absence of ST-segment elevation and when concomitant correct QT prolongation is also present.
