A pacemaker is an electronic device that generates electrical impulses to the heart. They are designed for people who can not keep up and often beats properly because your natural pacemaker is not working properly. The artificial pacemaker is a cardiac pacing system that controls and monotoriza cardiac electrical activity and causes electrical impulses are triggered. There are two types of pacemakers: temporary and permanent. Permanent pacemaker implantation is done by subcutaneous implantation of the generator, while temporary pacemaker generator is implanted in the patient and can be done transcutaneously or intravenously.
