The pacemaker is an electrical device that helps stimulate heart stimulation by feeling normal heart pulses and sending impulses if needed to activate cardiac muscle and maintain a normal heart rate. Indications for implanting the pacemaker are made according to the guidelines of the European Cardiac Society. The most common indications are bradyarrhythmia. Depending on the type of arrhythmia and the clinical condition of the patient, there are devices that are different according to the electrical capabilities, the number of electrodes to be carried pulses, and the size of the device itself. The procedure is performed with anesthesia, the device is inserted under the clavicle, and above the chest muscle. As with other invasive procedures and with the implantation of a pacemaker, there is the possibility of some complications. The most common complications are pneumothorax, hematoma, infection and bedsore of the pacemaker bearing. (1) In University Hospital Merkur implantation of pacemakers has begun in December of 1997, in operation theater of General Surgery and after September of 2007 procedures are performed in operation theater in the Department of Cardiology. We will present a patient with pacemaker bearing bedsore.
