The precautions to be taken after pacemaker surgery include avoiding strenuous exercise, preventing wound infection, regular pacemaker programming, staying away from places with high magnetic fields, and treating pre-existing heart disease. After pacemaker surgery, it is necessary to pay attention to avoid excessive activity of the shoulder joint on the affected side, not to lift heavy objects within three months, and not to raise the upper arm over the head to prevent dislocation of the pacemaker electrode. The wound should be changed regularly to prevent infection, and bathing should be avoided for a short period of time after surgery. Pacemaker program control should be performed three months after discharge from the hospital, and then every six months to one year. Patients with pacemakers should stay away from magnetic fields to avoid magnetic fields interfering with signals, and patients with organic heart disease should have active treatment for the primary disease. Postoperative recovery of pacemaker patients is mainly appropriate exercise, the shoulder joint can do a small range of activities to avoid stiffness of the shoulder joint, but at the same time, we should pay attention to avoid too large range of motion. Diet should be based on light diet, avoid eating spicy food, and ensure smooth bowel movement. Patients with pacemakers must do a good job of daily care and adhere to the review, so as to effectively improve the prognosis.
