How long you can live with a pacemaker in place is generally determined by the severity of the patient’s condition and cannot be generalized. Pacemakers are mainly used for cardiac conditions such as weak heart contractions and cardiac arrests, such as atrioventricular block, acute myocardial infarction, and sinus node insufficiency. After installing a pacemaker, most of the patients’ conditions will improve, and they can also prolong their lives, and some of them may even be cured without affecting their life expectancy. However, if the patient himself is older and accompanied by other serious underlying diseases, it will also affect the life expectancy, and the exact duration of life depends on the severity of the patient’s condition. It is recommended that patients with pacemakers have regular follow-up visits to the hospital to monitor the function of the pacemaker. If there are symptoms of discomfort, go to the hospital for treatment.
