Post-pacemaker surgery generally does not require monitoring in the monitoring unit and observation in the general ward is sufficient, unless other factors requiring monitoring are present. Local wound sandbag compression is applied for 4-6 hours, and after 24 hours medication can be changed and the wound observed. Postoperatively, the patient should move the forearm on the side of the implanted pacemaker in small increments or give massage to the upper extremity. The arm on the side of the implanted pacemaker is not overly stretched, but may be moved in a small range to prevent thrombosis, especially in elderly patients. Pacemaker implantation is relatively less invasive, so postoperative pain is generally not severe and few patients require analgesic medication. Patients are allowed to move around on the second postoperative day and bed rest is not absolutely required. The postoperative diet is normal and does not require any special restrictions, with light and easily digestible food. Postoperative intravenous prophylactic antibiotics are given for 3 days to prevent infection. Patients can be discharged from the hospital in 3-5 days for wounds that do not require stitch removal with general intestinal sutures. Wounds closed with regular sutures can be discharged after 7-10 removal of sutures, or they can be discharged 3-5 days after surgery and subsequently return to the hospital to have their sutures removed. Most patients can regain strength quickly and generally have mild discomfort at the incision site on the 1st postoperative day, which will then disappear. In the weeks following surgery, it is recommended to: 1. avoid elevating the shoulder and arm on the side of the pacemaker for several days after surgery; 2. do not apply direct pressure on the pacemaker, e.g. do not press on the pacemaker site or play with it; 3. check the incision site and contact the doctor immediately if there are signs of infection, e.g. localized fever, pain, discharge, etc.; 4. contact the doctor immediately if the following symptoms occur : dyspnea; whirling dizziness or syncope; persistent isokinetic weakness; chest pain; persistent eruption; edema of the wrists and ankles as well as the legs, arms and ankles. Some time after the pacemaker implantation, usually within a month, your doctor will give you an insurance card, which is like another ID card for you and should be kept. The insurance card will register the main information about your implanted pacemaker, the number of years of insurance coverage for the work of the pacemaker, the name of the hospital where the pacemaker was implanted and the doctor, etc. As long as you carry this card with you wherever you go in the city, the pacemaker follow-up doctor at each hospital will understand the type of pacemaker you have installed and the main information about it, and can learn about the condition of your machine by telemetry. You can also find out the approximate life span of your pacemaker from the card so that you can replace it in time before the machine runs out of power. In addition, you should carry this card with you when flying, as the machine inside you will alert you when you pass through security, so you should present it beforehand to avoid unnecessary hassles. Most doctors recommend that pacemaker patients carry a card documenting their disease status or a pacemaker insurance card so that others can know the condition of their machine in case of an emergency.
