1 Intro
2 Electrocardiogram ( Ecg ) Signals
The Electrocardiogram (
Ecg
)
•
Ecg
: electrical manifestation of heart activity recorded
from the body surface
•
monitoring of heart rate
The
Ecg
signal can be recorded fairly easily with surface
electrodes placed on the limbs and/or the chest, see pages 6 – 16
below.

3.12 Documenting Source Code
Documenting the source code is very important that other users of the code are able to understand
it. In this documentation Doxygen has been used. Listing
3.2 shows the used commands for
Doxygen. After running Doxygen a html help is generated. It is stored at
CD:/code/doc/html/index.html .
