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.
应激性心肌病是一种急性心脏疾病,其特征为左心室心尖部和心室中部短暂性收缩功能障碍。应激性心肌病已记录的心电图表现包括ST段抬高或T波倒置。这些心电图表现包含在应激性心肌病的诊断要求中。本文介绍了两例非典型心电图表现的病例,均为传导系统疾病及其可能机制。应考虑更改应激性心肌病的诊断标准,以纳入这些变异的心电图表现。
