Hello,Pacemakers do have an internal beeper system. The beeper starts beeping when the battery gets pretty low so you know to get yourself to the doctor right away.
A standard pacemaker battery usually lasts around 6-10 years. The battery strength should be checked regularly every 6 months. If you hear a beeping sound coming from your pacemaker, you should call your doctor right the way.
when you say right away do you mean that i should go to the hospital are see my Dr in the morning
