What is a NIPS Test?

NIPS, a non-invasive programmed stimulation, is a procedure during which your implanted cardiac defibrillator is tested and programmed to ensure that it functions optimally for you. This procedure may be done periodically throughout the life of your device and in response to changes in your overall health or in the medications you are taking.

The procedure involves artificially accelerating your heart to determine whether or not your device responds appropriately. You will be given mild sedation for the procedure. Expect to be in the clinic for several hours and plan on having someone available to drive you home after the procedure.

Why is this test Performed?

This procedure is done to make sure that your AICD will work appropriately when you need it. We also want to make sure the energy required does not drain the battery. We do this procedure to verify all of the above!

 If you are on Coumadin or warfarin, your blood needs to be thin enough to prevent clots from forming during the procedure, so a protime/INR will be checked. The INR needs to be at least 2.0 or higher for at least 4 consecutive measurements in most cases. 

Your doctor will discuss the risk and benefits and any alternatives with you in regards to having the cardioversion.  Please call the office at any time if you have questions or concerns in order to avoid delays or postponements.
