  The purpose of the Evaluating ECG capturing using sound-card of PC/Laptop is
provided portable and low cost ECG monitoring system using laptop and mobile
phones. There is no need to interface micro controller or any other device to
transmit ECG data. This research is based on hardware design, implementation,
signal capturing and Evaluation of an ECG processing and analyzing system which
attend the physicians in heart disease diagnosis. Some important modification
is given in design part to avoid all definitive ECG instrument problems faced
in previous designs. Moreover, attenuate power frequency noise and noise that
produces from patient's body have required additional developments. The
hardware design has basically three units: transduction and conditioning Unit,
interfacing unit and data processing unit.The most focusing factor is the ECG
signal/data transmits in laptop/PC via microphone pin. The live simulation is
possible using SOUNDSCOPE software in PC/Laptop. The software program that is
written in MATLAB and LAB-View performs data acquisition (record, stored,
filtration) and several tasks such as QRS detection, calculate heart rate.
