Takotsubo Cardiomyopathy (TC) is a syndrome characterized by reversible left ventricular dysfunction in the presence of possible emotional or physical triggers but without evidence of obstructive coronary artery disease. It has become increasingly reported worldwide and is associated with significant morbidity and mortality. TC may present with an array of electrocardiographic (ECG) findings. These ECG findings, if accurately interpreted, can play an important role in the diagnosis and risk stratification of this syndrome. In the last three decades since the disease was first described, multiple diagnostic criteria have been established. The key diagnostic tools for TC include clinical symptomatology, cardiac biomarkers, non-invasive cardiac imaging, and coronary angiography. The ECG findings in TC can be variable, however, some ECG scores have been proposed in association with TC with reasonably good diagnostic sensitivity and specificity. This article aims to provide a succinct review of important electrocardiographic findings associated with TC and its impact on clinical outcomes.
