Elderly people over 80 are generally recommended to be fitted with a pacemaker for treatment if their condition is compatible and there are no contraindications, which need to be decided by the doctor after taking into account the patient’s condition. Pacemakers are mainly used for the treatment of sick sinus node syndrome, third-degree atrioventricular block, and other serious heart diseases that lead to a decrease in heart rate and risk of sudden death. Pacemakers can be used to treat elderly people over 80 years of age if there are no specific contraindications. However, it is important to note that the use of pacemakers is strictly prohibited in patients with acute infections, multiple organ failure, and bleeding disorders. Therefore, before undergoing pacemaker surgery, it is necessary to carefully cooperate with professional doctors to carry out relevant examinations, strictly follow the doctor’s instructions for preoperative preparation, and pay attention to the observation of physical condition after the surgery, regular review, and follow up in case of discomfort.
