Inserting a permanent pacemaker is regarded as a less invasive surgery. The preferred method is transvenous access to the heart chambers while under local anesthetic, most frequently through the subclavian vein, cephalic vein, internal jugular vein, or (rarely) femoral vein. Usually, the operation is carried out in an operating room (OR) or a cardiac catheterization lab. In the infraclavicular area, the pacing generator is normally positioned subcutaneously. On rare occasions, pacemaker leads are surgically implanted through a thoracotomy, and the pacing generator is positioned in the abdomen. A pacemaker insertion is the implantation of a small electronic device to assist control sluggish electrical issues with the heart. This device is often positioned in the chest, right below the collarbone. To guarantee that the heartbeat does not drop to a riskily low rate, a pacemaker may be advised. Electrical currents, which typically follow a certain circuit within the heart, stimulate the heart, which is essentially a pump consisting of muscular tissue. The sinus or sinoatrial (SA) node, a small mass of specialized tissue situated in the right atrium (upper chamber) of the heart, is where this regular electrical circuit starts.
