Heart Condition Telediagnosis via Bio-Signals Surveillance Workbench Based on Simple Mail Transfer Protocol Technique

Abstract

This article leads to the implementation and development of a Laboratory Virtual Instrument Engineering Workbench-based vital signs surveillance system for cardiovascular patients based on the Simple Mail Transfer Protocol technology. There are three main parts comprising the designed device, the first portion is a lap (circuit) built utilizing a hardware amplifier (AD620) called an electrocardiogram amplifier lap. Then comes the signal-conditioning lap with a practical amplifier (LM741). The second portion, is the signal conversion part from an analog signal to the digital signal using a data acquisition card. Moreover, cardiac data is processed and digital filtering techniques are performed to eliminate artifacts (noise) from the electrocardiogram signal acquired through the Laboratory Virtual Instrument Engineering Workbench system. Additionally, after preprocessing the cardiac signal the developed algorithm is utilized to calculate the heart-rate and analyze the heart condition (analyze the arrhythmia condition). In order to make the current labor more effective and attractive, Simple Mail Transfer Protocol technology has been added for remote diagnosis and monitoring purpose the state of the electrocardiogram signals easily over the internet, where the Simple Mail Transfer Protocol technology benefits is low-cost and effective in telediagnosis, which was previously a major problem overcome by this technique.
