Patients are allowed to exercise freely to the extent of major advances in electronics, and now virtually all pacemakers are powered by a variety of lithium batteries. The life of the lithium pacemaker varies from 7–10 years. Each patient is given a card that documents the type, model, serial number, date of installation, and approximate life of the pacemaker and should carry the card at all times and wear a pacemaker awareness bracelet.
Pacemaker patients are strongly advised to attend a pacemaker clinic for follow up in order to detect the rare occurrence of intolerance. Many are able to jog one to five miles daily and do similar exercises if angina or heart failure are not present. A patient with a pacemaker can lead a normal life.
