Overview
Electrocardiogram
The EKG findings are often confused with those of an acute anterior wall myocardial infarction.[1][2] While the ECG may reveal ST-segment elevation, it may also reveal non-specific ST/T wave abnormality, usually in the precordial leads. The 12-lead ECG alone is not helpful in differentiating apical ballooning syndrome from a traditional thrombotic ST-elevation myocardial infarction. Evolutionary changes occur over 2 to 3 days that are characteristic and include resolution of the ST-segment elevation and development of diffuse and frequently deep T-wave inversion.
The diagnosis of takotsubo cardiomyopathy may be difficult upon presentation. The EKG findings are often confused with those found during an acute anterior wall myocardial infarction.[1][2]
