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.
