Pacemaker testing/ programming
This is a test that evaluates the functioning of the implanted cardiac device and adjusts its settings if necessary. Regular testing helps ensure the safe and effective operation of the pacemaker in the long term.
What is it?
A pacemaker (ECG) is a small medical device that is implanted under the skin, most often in the shoulder area. Wires (electrodes) extend from the device, which connect to the heart and help maintain its rhythm by stimulating the heart when it is too slow. There are also ECGs that are equipped with additional functions and are implanted not to help with a slow rhythm, but to prevent adverse cases of a fast, irregular heart rhythm.
ECG testing and programming is an examination during which the functioning of the implanted cardiac device is evaluated, its recordings are analyzed, and, if necessary, settings are adjusted.
Regular testing of the stimulator is essential to ensure its effective and safe operation in the long term.
How is it done?
During the test, the patient sits or lies in a comfortable position. A special programming device is placed on the skin above the stimulator, which communicates with the stimulator in a contactless manner, reading the stored information.
During the procedure doctor can check parameters such as:
-
heart rate recordings,
-
stimulation frequency and effectiveness,
-
electrode operation,
-
stimulator energy reserves (battery life).
If necessary, the doctor can adjust the pacemaker settings, such as changing heart rate limits or pacing modes, to ensure optimal heart function and patient well-being.
The procedure takes 15 to 30 minutes and does not include a doctor's consultation. If additional recommendations regarding medication, treatment, or follow-up are needed after the examination, a separate doctor's consultation should be scheduled - either at the same time as the examination (if known in advance) or it can be scheduled after the examination.
When is it needed?
Pacemaker testing and programming is most often performed by:
-
for regular monitoring after pacemaker implantation;
-
if the patient complains of weakness, dizziness, palpitations or fainting;
-
to assess the performance of the stimulator and the remaining battery life;
-
after changing the stimulator parameters or replacing the electrodes;
-
before planned medical procedures (e.g., surgeries, magnetic resonance), if adjustment of the stimulator settings is required;
-
upon advice of a doctor as part of the patient's regular heart health check-up.
How to prepare?
No special preparation is required for the pacemaker test and programming. However, there are some suggestions that will help the examination go smoothly:
-
Take your stimulator passport or documents issued after implantation with you – they contain important information about the device model and settings.
-
If available, also bring a description of the previous pacemaker test so that the doctor can compare the results over time.
-
Continue taking your medications as usual unless your doctor has given you other instructions.
-
Bring a pre-prepared list of medications you are taking, indicating the names and dosages of the medications.
-
Choose comfortable clothing that easily uncovers the place of the stimulator (usually the upper chest or shoulder area).
-
If you are sent for additional tests on the same day (such as an X-ray or MRI), inform the staff that you have a pacemaker.
-
Before the test, inform your doctor if you have noticed any changes in your heart rate, dizziness, palpitations, or episodes of weakness — this will help to more accurately assess the functioning of the pacemaker.
