Tako-Tsubo-like syndrome during anaphylactic reaction

摘要

Tako-Tsubo's syndrome (apical ballooning or broken heart syndrome) is a reversible left ventricular dysfunction due to apical asynergy that occurs typically after sudden emotional stress in a subject without coronary disease. It is characterized by acute onset of chest pain or dyspnoea or both and is associated with electrocardiographic changes such as ST segment elevation and/or T wave inversion. Myocardial biomarkers may be normal or slightly elevated.
