AbstractWe describe a case of out-of-hospital Cardiac Arrest (CA) in a patient with Barlow's Syndrome (BS) and features of Stress Cardiomyopathy (SC) (or Apical Ballooning Syndrome or Tako-Tsubo). The patient experienced CA during physical stress and was resuscitated thanks to DC-Shock. The Electrocardiogram (ECG) after resuscitation was unremarkable. In the reported case the documented severe hypokalemia, with the physical stress, could have triggered the CA, probably of tachyarrhythmic origin. However, in the reported case, the echocardiographic, coronarographic and ventriculographic features, were surprisingly indistinguishable from those of the SC. In conclusion it is impossible to say if, in our patient, the CA has been caused by BS or by SC. However, even if CA has been probably caused by the BS, we hypothesize that the CA, in its turn determined, might have caused the SC via stress mechanisms. In few words, the CA is a complication of SC, but should probably be regarded also as a cause of SC.Copyright 2008 Elsevier Ireland Ltd. All rights reserved.
