ECG Monitoring System Based on Microcontroller

Abstract

Health monitoring systems becomes a hot topic and important research field. Electrocardiogram (ECG) signal is a diagnoses tool that measures and records the electrical activity of the heart, taking care of patient’s health. Therefore, monitoring this signal becomes a necessary need to take care of human health. In this paper, two procedures are proposed; first, monitoring the ECG signal, second for sending the signal of monitoring patients and ECG data through Serial communication port to the other pc or nurse. AT89C51 microcontroller uses to perform these procedures including all the necessary connections of the microcontroller with other components and programming the microcontroller using assembly language to send the signal serially. At both transmitting and receiving sides, the signal was gives the same setting of baud rate, stop bits, number of data bits, parity to ensure secure arrival of data without any lossless.
