What is Device (Pacemaker and Defibrillator) Interrogation?
Your pacemaker or defibrillator has the ability to communicate through the skin with a programmer we have in the office. We perform this interrogation by placing a wand over your chest where the device is located. It takes only 10 or 15 minutes.
What are the indications for the procedure?
We routinely evaluate the programming of your device and confirm that the battery and wires (leads) are functioning appropriately. Device interrogation can be done routinely in the office setting.
How is it done?
We place a wand over your device that is linked to a special computer called a programmer. When the programmer and the device communicate, valuable information can be obtained from the memory of your device and we can change the programmed settings if needed.
Typically we start by evaluating the remaining lifespan of the battery and we can usually give you some idea about how long the battery will last. We test the function of the leads and make sure they conduct electricity both to and from your heart. We can also modify the programmed parameters to better suit your heart’s individual needs. If you have any questions or concerns about your pacemaker or defibrillator please bring them up and we can address them.
How do you prepare for the procedure?
No preparation is needed. In the office, our staff will have the necessary equipment to check your pacemaker or defibrillator. At home, you will also have special equipment to transmit tracings over the phone.
What are the risks of the procedure?
There are little or no risks of the procedure. With testing occasionally you can feel some mild lightheadedness with the interrogation and testing of you device.
