Variable conduction system disorders in takotsubo cardiomyopathy: a case series.

Takotsubo cardiomyopathy is an acute cardiac condition characterized by transient systolic dysfunction of the left ventricular apex and mid-ventricle. Documented EKG presentations for Takotsubo cardiomyopathy include ST-segment elevation or T-wave inversion. These EKG presentations are included in the diagnostic requirements for Takotsubo cardiomyopathy. This paper presents two cases of atypical EKG presentations, both conduction system disorders, and their possible mechanisms. Changes to the diagnostic criteria for Takotsubo cardiomyopathy should be considered to include these variant EKG presentations.
