A pacemaker is an electronic device that is placed inside your body to monitor your heartbeats. Your heart beats when it receives signals from your hearts electrical system. When you are active, these signals speed up to move your blood faster. When you are resting , signals return to a slower pace. Occasionally your heart signals do not work correctly. The electrical system may send signals that are either too slow (bradycardia), too fast (tachycardia) or no signal at all (sinus pause). When problems with the electrical system of your heart exists, a pacemaker can help. The pacemaker keeps tract of your heartbeat and, when necessary, generates electrical signals similar to the heart’s natural signals. When the heart’s system misses a signal, the pacemaker sends a signal to replace it. These signals will keep your heart beating at the right pace.
Your cardiologist will choose the type of pacemaker that’s best for you. A pacemaker with one lead is called a single-chamber pacemaker. A pacemaker with two leads is called a dual-chamber pacemaker.
Placement of the pacemaker is a simple surgical procedure. The devices are usually inserted near the right or left shoulder. The pacemaker’s settings are programmed to help your heart beat at a rate that’s is right for you. The incision is closed and covered with a sterile dressing. Your heart signals and pacemaker will be monitored while you are in the hospital. Your incision will heal in about a month.
