CardioMessenger II-S Introduction

3

Introduction

Dear patient:
You have received a pacemaker or implantable

cardioverter-defibrillator (ICD) with the
additional Home Monitoring function by
BIOTRONIK. With Home Monitoring, the state
of your heart's health and your implant are
surveyed on a daily basis while you are at
home. Your physician can catch up at regular
intervals on how your heart is doing.

How Home Monitoring works

Your implant is equipped with a special
transmitter (1). Usually at night, the
transmitter sends daily information on your
heart to the patient device, your
CardioMessenger (2).

The transmission power from your implant is
low and does not impair your health in any way.
Its limited transmission range, however,
requires the use of the CardioMessenger.

The CardioMessenger collects the information
received from the implant and automatically

CardioM essenger_II-S_en.book Page 3 T uesday, May 6, 2008 1:11 PM

Introduction

4

transmits it to the BIOTRONIK Service Center
(4) as encoded messages via a mobile
connection (3).

Here, the messages are decoded and made
available for viewing by your physician (5) on a
protected web site.

Based on the information received, your
physician can decide if your implant is best
configured, or if the therapy needs
adjustments. In this way, Home Monitoring
serves as a practical diagnostic aid to your
physician.

table. The bedside table is suitable because it
usually meets the following conditions:

2

The CardioMessenger is placed on a solid
base and cannot fall.

2

The distance to the implant is less than 2
meters so that regular data transmission at
night is assured.
At the same time is the distance to the
implant more than 20 centimeters and the
CardioMessenger has no influence on your
implant.

Warning!

The distance between CardioMessenger and
implant has to be at least 20 centimeters.

The CardioMessenger contains a mobile
module ("Mobile"). In order to prevent any
interferences of the implant, you have to
keep the prescribed minimum distance
between implant and cellular phone also to
the CardioMessenger.

a) Field strengths from fixed transmitters, such as base stations for radio (cellular(/cordless) telephones and land mobile radios, amateur

radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy.
To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the CardioMessenger is used exceeds the applicable RF compliance level above, the
CardioMessenger should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the CardioMessenger.

b) Above the frequency range of 150KHz to 80MHz, ensure that field strengths are less than 3V/m.
