An 83-year-old female patient with symptomatic atrial fibrillation was referred to the Department of Cardiology for a scheduled electrocardioversion. Because of a junctional escape rhythm after the electrocardioversion she received a DDD pacemaker which was complicated by dyspnoea and ST-segment elevations in the inferior and precordial leads. Because of suspicion of an acute myocardial infarction she was transferred to a PCI centre. The coronary angiogram showed no abnormalities. In the initial phase, an echocardiogram was performed. The echocardiogram showed apical akinesis and a reduced left ventricular function. During follow-up left ventricular function improved and was completely normal nine weeks after the event. The clinical picture was interpreted as a takotsubo cardiomyopathy after a pacemaker implantation. (Neth Heart J 2009;17:487-90.)
