Since 1958, when the world’s first pacemaker was created, countless patients with arrhythmias have benefited from pacing therapy. Pacemaker therapy has evolved from a simple life-sustaining approach to one that maximally mimics the function of the human heart’s conduction system to achieve a state close to the ideal of a normal human life. In China, with an increasingly aging population, more and more patients are requiring pacemaker therapy. Pacemaker therapy is a mature surgical technique that has long been performed in major hospitals across the country, and clinical electrophysiologists are slowly shifting their focus from surgery to postoperative patient management. Patients with pacemaker implantation are advised to keep their wounds clean and to contact their physicians as soon as possible if they notice redness, swelling, pain, fluid leakage or fever. 2. Pacemakers cannot cure the primary diseases of the heart, such as hypertension and coronary heart disease. Therefore, you should not be paralyzed and should adhere to the necessary medication. 3. Postoperative activities should follow the principle of gradual progress, especially during the first three months after surgery, avoid raising the arm on the operated side and moving it substantially to prevent displacement of the pulse transmitter and the lead. It is worth mentioning that it is also wrong for some patients to avoid activities after surgery because they are overly concerned about the displacement of the pacing system, which will affect the normal activities of your arm and even produce pain, blood flow obstruction and other negative consequences. 4. One month, three months, six months and one year after surgery are the regular follow-up periods, and you should follow up on time. If you are a pacemaker-dependent patient, you should contact your physician as soon as possible for replacement to avoid malignant clinical events. It is recommended that you get used to recording your pulse every morning and seek medical attention if there are any major abnormalities. 5. Commonly used home appliances such as refrigerators, microwave ovens, cell phones, etc. do not affect the normal operation of the pacemaker. You should avoid contact with appliances that have direct vibration with your body or issue electromagnetic waves, such as electric massage beds, induction cookers, electric blankets, electric drills, lawn mowers, etc. Try to avoid being close to areas with high magnetic fields, such as large motors, substations, radar antennas, TV and radio transmitting antennas, high-voltage cables or industrial magnets. Some medical equipment such as surgical electric knives, defibrillators, gamma-ray instruments, transthermal therapy instruments, shock lithotripters and transcutaneous electrical stimulators may interfere with the work of the pacemaker, and you should inform your physician about the installation of pacing before treatment. Even if you have an anti-MRI pacemaker, you should contact your physician and the engineer concerned and prepare the program before the examination. 6. If your pacemaker is equipped with a function that slows down the heartbeat at night, you should contact your physician and adjust the relevant parameters before traveling to a country with time differences. As the pacemaker is made of metal, you should present the pacemaker implantation card as proof at the airport when passing through security. In addition, in case of an emergency, the pacemaker implantation card will help the medical staff to know your data in order to make a correct decision. Finally, please keep in effective contact with your surgeon or the relevant team after the pacemaker implantation so that problems can be detected and dealt with at the first opportunity.
