Also, avoid leaning over the open hood of a running car because its electrical field can interfere with your pacemaker. It is important to have your pacemaker checked on a regular basis. You should receive by mail a telephonic transmitter from Ray-Tel with instructions within a month of discharge. Ray-Tel will set up an appointment to check your pacemaker on a regular basis. If they identify any problems with your pacemaker, your doctor will be notified.
