The risk of pacemaker installation in 80 year old patients whose condition requires it is relatively low because pacemaker installation is a minor, minimally invasive procedure and the benefits far outweigh the risks for most patients. Although 80 years of age is an advanced age, with the current advances in medical technology, pacemaker installation in 80 year olds is relatively safe. The conditions that require pacemakers are commonly seen in third degree AV block, sick sinus node syndrome, etc. These conditions are more dangerous and can be easily treated with pacemakers. These conditions are more dangerous and can lead to cardiac arrest, fainting, etc. So the benefits that a pacemaker installation can bring to a patient far outweighs the risks it can cause. Pacemaker surgery involves placing electrodes into the atria or atria and ventricles by puncturing a blood vessel, and placing a battery pack under the skin through a small incision in the chest. The patient is conscious throughout the procedure and can be out of bed three days afterward. So the risk of installing a pacemaker in a senior citizen is relatively low.
