Design of a Portable Device for ECG Signal Acquisition And its Transmission Using Bluetooth For Diagnostic Analysis

Abstract

In the period of developing innovation, the anticipation to live more has expanded many-a-folds. If a patient prefers to visit a doctors on a day to day basis for tests like stress level detection, ECG or blood pressure tests the expenditure becomes too high. It even gets worse in remote areas where the costly equipment for the mentioned test are not available. In this paper idea about a portable device is presented, which is meant to be a portable and easy to use medical equipment for acquiring ECG signal. The raw signal generated on the human body surface due the polarization and depolarization of heart is acquired through a hand held module and transmitted to a laptop/mobile for analysis. In this way regular health check can be done with ease. Using a 3 lead ECG sensors, real time data is obtained directly from the subject using a DAQ (Data Acquisition Module). Then it is transmitted using Bluetooth and microcontroller, and the final analysis and display part is done on the computer/laptop/phone. Hence a low cost, low power consuming device with higher connectivity options can make great changes in health care sector
