Takotsubo syndrome (TS) is a recognized acute cardiac disease entity. The defining feature of TS is the regional circumferential pattern of left ventricular wall motion abnormality (LVWMA) with good contractions in the remainder of the left ventricle resulting in a conspicuous ballooning of the left ventricle during systole. In about 70 of cases, TS is preceded by an emotional or a physical stress factor. Externally administered epinephrine or innate elevation of epinephrine in diseased condition as pheochromocytoma has been reported to trigger TS. Herein, we report the case of a 42-year-old man with epinephrine-induced TS with 3 important features: immediate induction of the disease after epinephrine administration and rapid recovery; the mid-basal pattern (inverted) TS pattern, which may be seen in one thirds of patients with epinephrine-induced TS; and the post-extrasystolic augmentation of the stunned myocardial contractility.
