It delivers electrical pulses to the heart to ensure that it beats at a regular and steady rhythm. This can be necessary for individuals who have an abnormal heart rhythm, also known as an arrhythmia. Pacemakers are typically used for conditions such as atrial fibrillation, bradycardia, and heart block. The pacemaker consists of two main components: a pulse generator and one or more leads. The pulse generator contains a battery and a computer circuit that controls the electrical pulses. The leads, which are thin, flexible wires, are placed in the heart to deliver the electrical signals. The pacemaker can be programmed to deliver different electrical impulses depending on the specific needs of the patient. Pacemaker implantation is typically performed using local anesthesia, and the device is usually placed just under the skin below the collarbone. The leads are threaded through a vein and are carefully positioned in the heart. The procedure is generally considered safe and has a high success rate. Pacemakers have significantly improved the lives of millions of people by reducing symptoms, preventing fainting, and reducing the risk of sudden cardiac death. They have also allowed patients to resume normal activities without limitations. However, like any medical device, there are risks associated with pacemakers, including infection, bleeding, and problems with the leads or pulse generator. The history of pacemakers dates back to the 1950s when the first battery-powered pacemaker was developed. Since then, there have been numerous advancements in pacemaker technology, including miniaturization, longer battery life, and remote monitoring capabilities. Overall, pacemakers have revolutionized the treatment of heart rhythm disorders and continue to be an important tool in cardiology.
