Introduction
After returning to the ward, patients who have undergone cardiac pacemaker implantation should primarily monitor their surgical wound to prevent contamination. They should wear cotton clothing and avoid wearing stiff or rigid garments. For the first month following implantation, vigorous activity of the ipsilateral limb is not recommended. Shoulder immobilization is advised—patients should avoid raising the arm above shoulder level or reaching for objects to prevent traction or displacement of the leads before they are fully embedded in the surrounding tissue.
The primary concern is infection—this is the most feared complication. Since surgery is performed in a sterile operating room, infection should rarely occur during the procedure itself. After returning to the ward, special attention must be paid to the surgical wound: regular, proper wound dressing changes are essential to prevent contamination, and the wound site must be kept clean and disinfected. Once the wound has fully healed, patients should wear soft, cotton clothing and avoid wearing stiff or abrasive fabrics.Device placement—whether on the left or right side—is determined by the physician based on the patient’s dominant hand (e.g., for right-handed patients, the device is typically implanted on the left side, and vice versa), to minimize interference with daily limb function.
Within the first month after implantation, vigorous activity involving the ipsilateral (same-side) limb is not recommended. Shoulder immobilization is advised; patients should avoid raising the arm above shoulder level or reaching overhead or backward (e.g., to retrieve objects), as this may exert traction on the leads before they have fully stabilized in the tissue, potentially causing lead displacement.Later on, if any unusual local symptoms develop—such as redness, itching, pain, swelling, or warmth at the implant site—patients should promptly seek medical evaluation to rule out complications. High-intensity sports should be avoided, especially those involving the implanted side (e.g., playing badminton with the ipsilateral arm). Following ICD implantation, swimming and other strenuous, contact-intensive sports should also be avoided.
Many patients inquire whether using mobile phones or induction cooktops may interfere with device function. Two key principles should be remembered: avoid exposure to strong magnetic fields and strong electric fields. Routine security screening devices, common household electrical appliances, and similar equipment generally pose no significant risk of interference. However, when using an induction cooktop, maintain a distance of at least 1 cm between the device and the cooktop surface.
