Pacemakers are usually permanent pacemakers. After the pacemaker is installed, the heart rate can be restored to normal to supply the body’s needs, and the patient can usually live and work normally and survive for a long time after the pacemaker is installed. Some patients often worry about the short survival time after pacemaker installation, but there is usually no need to worry. After the pacemaker is installed, it is only necessary to follow the doctor’s advice and go to the hospital for regular reviews to ensure that the pacemaker is working well. Therefore, a pacemaker can survive for a long time and has only beneficial effects on the human body, but if the pacemaker does not work effectively without the advice of a doctor, it can also affect health. Therefore, patients are advised to go to the hospital for regular review to know if the pacemaker is working properly in order to survive for a long time and carry out normal work and life.
