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 microcontroller
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.
