The life expectancy of a pacemaker is generally around 6-10 years. The life span of a pacemaker is related to its type, function, frequency of use, number of discharges, etc. and cannot be generalized. For pacemaker-dependent patients and special pacemakers such as ICDs, the life span of pacemakers is relatively short due to their high discharge volume; if the pacemaker inhibition increases or the voltage increases, the life span of pacemakers can be affected. Therefore, patients are advised to visit hospitals regularly for follow-up visits to adjust the pacemaker parameters in time to reduce its power consumption and prolong its life span.
