Lab VIEW is the Laboratory Virtual Instrument Engineering Workbench tool which is used for continuous monitoring of an ECG signal that is Electrocardiogram. This Electrocardiogram is the extremely powerful diagnostic and monitoring system which is used in now a days medical practices. By monitoring any person’s ECG we can predict many diseases which are related with heart like Sudden Cardiac Arrest (SCA), Pulmonary diseases, Cardio Vascular diseases (CVD) etc. This ECG signal is generated due to nerves impulse stimulate to the heart. Due to the electrical activity of the heart, a very small current diffuses on surface of a body which build the small voltage drop of 0.01 mV to 3 mV in amplitude. This small signal can be further processed through instrumentation amplifier where large signal are eliminated and small signals are only amplified and given to the filters where noise can be removed from this ECG signal. The pure ECG signal from the filter is in analog form which can be given to the NI myDAQ to convert it into digital signal. This digital ECG signal which can be finely sampled at specific time interval into LabVIEW for its continuously monitoring. LabVIEW is used as the Graphical User Interface in which anyone can monitor this ECG signal very easily. This system is cost effective for clinical applications. It will save the patients history in LabVIEW with the help of excel sheets which will helps in future.
