Electrocardiogram (EGG) has long been used as an important medical tool in
monitoring patient's heart activities. In some cases, the patient has to go to
the medical center very often to record their EGG for the diagnostic of the
physician. This thesis describes the design and development of an
electrocardiogram (EGG) recorder for single-lead recording that enables the
recording of EGG at home and development of software to receive the EGG
data from the recorder. The EGG data is saved in a compressed format for
easy transmission over the Internet. The EGG recorder is a battery-powered
device and its design emphasises on low power consumption. The EGG
recorder is used as a peripheral connected to the computer via RS-232 port.
The software was developed by using Visual G++ programming language. At
the end of the project, an EGG recorder has been constructed and its
characteristics have been tested. The software can display the EGG data
and clearly show the P, Q, R, S and T waves for diagnosis
