The Critical Role of Lambda-Shaped QRS-ST-T Wave Fusion ST-Elevation in Diagnosing and Managing Takotsubo Cardiomyopathy: A Case Report and Review of Literature

Abstract

Stress-induced cardiomyopathy, commonly known as Takotsubo cardiomyopathy (TCM), is a clinical syndrome characterized by acute and transient ventricular systolic dysfunction that often presents with chest pain and may resemble an acute coronary syndrome. This case report discusses a complex clinical scenario involving an adult female with severe depression who attempted suicide through drug overdose, subsequently developing serotonin syndrome. Her clinical presentation was further complicated by the emergence of a unique lambda-shaped triangular QRS-ST-T waveform fusion ST-elevation electrocardiographic (ECG) pattern closely mimicking an anterolateral occlusive myocardial infarction. The study delves into the clinical implications of this unique ECG pattern in TCM, providing valuable insights into diagnosing and treating such complex cases. This case underscores the importance of recognizing diverse manifestations of TCM and its potential for severe cardiovascular complications.

Diagnostic challenges between takotsubo cardiomyopathy and acute myocardial infarction—where is the emergency?: a literature review

“…LVOTO is present in about 20% of the patients with TC [2]. LVOTO assessment by TTE or LV invasive hemodynamics is important for therapeutical management [20]. LV end-diastolic pressure has a prognostic impact and is a good predictor of complications during hospitalization [21].…”
