What You Should Know
Trouble shooting pacemakers is done by using a compatible programmer for the specific type of pacemaker. The programmer is used to monitor surface ECG and to determine the patient's underlying heart rhythm. The pacemaker is interrogated by placing a wand on the chest over the pacemaker battery. This allows the nurse to check the programmed measurements. A computerized printout is scanned to check for lead wire or battery failure.

Sensing or threshold checks are done yearly unless otherwise indicated. The measurement of these settings determines the margin of safety while ensuring the longevity of the generator (battery). The measurements checked allow for assessment of the heart rate response to activity.

The sensor-rate program provides an overview of this sensor responsiveness. This shows how the patient actually uses the pacing system.

To evaluate a pacemaker, a computerized print out is complied during every pacemaker/ICD check. This is read by the physician who is responsible for following your pacemaker care.

If problems are detected, the physician who follows you with the pacemaker will be notified of problems with the pacer device. A chest X-ray may be ordered to check for lead placement or fracture of the lead wire. Further investigation of the problem will be ordered by the physician. A company representative may be brought in to further evaluate the problem also. Reprogramming may be done if deemed necessary or the pacemaker and/or wire may have to be replaced.

If you are scheduled to have a checkup, you should register with Outpatient Registration on the first floor of the Medical Center 15 minutes before your scheduled appointment. Following registration, you will be directed to the Pacemaker Clinic in Cardiopulmonary Services on the second floor.
