•ECG Holter: Graduation Project Grade: Excellent
Holter system provides 24/48 hours of continuous ECG recording and
analysing for detecting heart rate abnormalities which may otherwise go undetected.
In our project we designed a prototype of the holter capable of recording ECG and save
data on a multimedia card .
GENERAL DESCRIPTION OF SYSTEM:
The ECG signal is first collected by the mean of three electrodes placed on body which
measure potential difference on specific location on the human body, and they form one
In The second stage the ECG is amplified and filtered of noise in the ECG
amplification circuit and we get asignal in the range from 0.05 to 150 HZ.
Signal is then fed to an analog to digital converter to get the digital output entered to
The microcontroller is then send data to the memory card (multimedia card) using SPI
mode where it is saved.
For the displaying of the signals (in a specified period e.g. 24 hours) we saved we
transfer data through serial port to PC where a further processing and analysis can be
We choose AT89C55WD which is 8051 core microcontroller because of its 20K bytes of
Flash programmable read only memory since our HEX code file is about 6KB, and its
My role was the microcontroller interfacing as collecting data from ADC 0804& send it
to MMC in first mode,then sending the data to SPI in the second mode.
