Abstract

• In this work, the MATLAB software has been developed to measure electrocardiogram (ECG) signal and to analyze the measured signals. The measurement system consists of three electrodes connected to the ECG sensor (AD8232), data acquisition card (Atmega328 Board) and a laptopcomputer. The code for the data acquisition card is tested with the developed MATLAB software. The software includes acquisition of real time ECG data, ECG signal processing and calculating beat rate. The measured signals are recorded in the desired path of the computer. The results are compared with standard data and then show that the system yields equal results compared to the reference measurements for patients at rest. The usability of the system is excellent due to simple three-arm electrode solution. The system can be used for home health care application.
