We describe an atypical presentation of stress-induced cardiomyopathy - Takotsubo cardiomyopathy - in a 16-month-old boy previously diagnosed with cyclic vomiting and episodic hypertension. He developed features of cardiac failure and his echocardiogram showed left ventricular wall motion abnormality accompanied with elevated cardiac enzymes. Cardiac catheterisation showed no coronary arterial abnormality. Complete spontaneous recovery occurred 2 weeks after admission.
