A Pacemaker is a small device with two parts --- a generator and wires that's placed under the skin in your chest to help control your heartbeat. Pacemakers are implanted to help control your heartbeat and they can be implanted temporarily to treat a slow heartbeat after a heart attack, surgery or overdose of medication. In certain cases, Pacemakers can be implanted permanently to correct a slow heartbeat or in some cases, to help treat heart failure. Surgery to implant the pacemaker is usually performed while you're awake and takes a few hours. Most Pacemaker surgeries are done using local anesthesia to numb the area. During the Pacemaker Surgery, one or more flexible, insulated wires are inserted into a major vein under or near your collarbone and guided to your heart with the help of X-ray images. One end of each wire is secured to the appropriate position in the heart, while the other end is attached to the pulse generator, which is usually implanted under the skin beneath your collarbone. Pacemaker Treatment is a standard treatment for many conditions affecting the heart's electrical system and by preventing a slow heart rate, Pacemakers can treat symptoms such as fatigue, lightheadedness, and fainting. After the surgery, the patient needs to stay in the hospital for 1-2 days and a return visit is scheduled by the Cardiologist to make sure that the Pacemaker's settings are correct. The cost of the treatment depends on the hospital stay required, surgery and doctor's fees.
