This application is intended only for educational purposes for those recipients of a pacemaker and/or defibrillator, and for health professionals. This application contains a list of objects that you can encounter, in the home - or outside - environment, or some diagnostic and therapeutic procedures usually present in healthcare environments. All of these are potentially able to generate an electromagnetic field that can affect the proper function of your pacemaker or ICD. For each area (at home or outside) you will find environments (like kitchen or bank) in which you will see numerous items listed; similarly in the healthcare area. Not all listed items are potentially risky and this will be indicated by a color code. A tutor will always be available to remind you of the meaning of the color codes. The App also has an item search system and moreover, it will give you the opportunity to tell us an object not found in order to include it in future updates. We hope this tool would help especially you, the patient, providing quick, simple and "at your fingertips" relevant information. The function of the App is to help pacemaker/defibrillator recipients, live life normally!
