1. Patients should know the frequency of pacemaker settings and the age of use. Patients should learn to count their own pulses and seek medical attention promptly when there are obvious changes in pulse rate or dizziness, weakness, syncope and other maladjustments. 3. The upper limb of the pacemaker should avoid excessive force or large amplitude movements, such as playing tennis or lifting weights, to avoid affecting the pacing function. 4. Avoid strong magnetic fields and high voltage, such as nuclear magnetism, laser, physiotherapy, electrocautery equipment, substations, etc., but household electricity does not affect the work of pacemakers in general. Once patients experience chest tightness, dizziness and other discomforts after contacting a certain environment or electrical appliance, they should immediately leave the scene or stop using the appliance. 5. Keep the pacemaker card (indicating the pacemaker type, brand, relevant parameters, placement date, etc.) properly and carry it with you when you go out to provide information for diagnosis and treatment in case of accidents. 6. Follow up regularly to test the function of the pacemaker. Generally, follow-up visits should be made every 3 months for the first year and every 6 months thereafter.
