Pacemakers include cardiac pacemakers, brain pacemakers, penile pacemakers, etc. Pacemakers are mostly seen in clinical practice. How long a patient can generally live after having a pacemaker depends mainly on the specific condition of the patient as well as his age and whether he has any combined complications, and the problem should be analyzed specifically. If a patient is fitted with a pacemaker because of a slow heartbeat or if the heart is prone to malignant arrhythmias when it is beating too slowly. Most such patients will live longer if they are successfully implanted with a pacemaker, but the exact duration varies from person to person. The life expectancy of the pacemaker is about 8-10 years. After 8-10 years, the patient should actively visit the hospital to review the status of the pacemaker and replace it. If the patient is older and has other serious underlying diseases, this can affect the patient’s life expectancy. Patients are generally required to be followed up once a month for the first six months after discharge after pacemaker fitting and every three months thereafter to measure pacemaker function. If you feel palpitations, chest tightness, dizziness or a slow pulse on self-test, you should immediately consult a doctor for regular follow-up.
