How can you maintain a heart pacemaker?

Regular visit to doc: There isn't much you can do to maintain the pacemaker because it is implanted under your skin-often left upper chest area. Its functions are programmed by your heart doc/surgeon and regular visit/assessment is essential to ensure proper fucntioning/battery life. Certain environment may affect it such as MRI machine etc..So, visit/inform doc regularly. Eat, sleep, exercise and live well. Good luck.

You don't: Pacemakers are hermetically sealed and require no maintenance. They do, however, require checks every 3-6 months to ensure normal function and normal depletion of the battery.
