3What is Home Monitoring?Dear Patient:You have received a BIOTRONIK pacemaker or implantable cardioverter-defibrillator (ICD) with Home Monitoring function. Home Monitoring pacemakers and ICDs are additionally equipped with a special trans-mitter. This transmitter automatically transmits medical and technical information to a mobile device, the CardioMessenger. The CardioMessenger works like a cell phone and automatically transmits the information received from your device as encoded messages to the BIOTRONIK Service Center.The transmission power from your device is low so as to not impair your health in any way. Since the transmission range is short, the CardioMessenger is needed to send the information to the BIOTRONIK Service Center.At the Service Center, the data are processed and can be viewed only by your physician on a secured Internet site in the form of a comprehensive report called a Cardio Report. Your doctor can use this Cardio Report to decide whether your device settings need to be updated or if your therapy plan needs to be changed. Thus, Home Monitoring serves as a practical diagnostic aid.CardioMessenger.book  Page 3  Thursday, January 5, 2012  1:13 PM

3What is Home Monitoring?Dear Patient:You have received a BIOTRONIK pacemaker or implantable cardioverter-defibrillator (ICD) with Home Monitoring function. Home Monitoring pacemakers and ICDs are additionally equipped with a special trans-mitter. This transmitter automatically transmits medical and technical information to a mobile device, the CardioMessenger. The CardioMessenger works like a cell phone and automatically transmits the information received from your device as encoded messages to the BIOTRONIK Service Center.The transmission power from your device is low so as to not impair your health in any way. Since the transmission range is short, the CardioMessenger is needed to send the information to the BIOTRONIK Service Center.At the Service Center, the data are processed and can be viewed only by your physician on a secured Internet site in the form of a comprehensive report called a Cardio Report. Your doctor can use this Cardio Report to decide whether your device settings need to be updated or if your therapy plan needs to be changed. Thus, Home Monitoring serves as a practical diagnostic aid.CardioMessenger.book  Page 3  Thursday, January 5, 2012  1:13 PM
