Tako-tsubo cardiomyopathy in a patient with pacemaker syndrome.
We report the case of a 71-year-old woman, with a dual chamber pacemaker (PM), in whom a PM syndrome, due to loss of atrial sensing and pacing, was associated with a tako-tsubo cardiomyopathy (TTC). The repositioning of the atrial lead immediately improved symptoms, whereas complete regression of left ventricular wall motion abnormalities occurred after 1 month. We hypothesize that haemodynamic and hormonal responses associated with a PM syndrome, such as increased levels of catecholamines, may account for TTC in our patient.
