摘要：The paper describes the development of a low cost and simple amplifier circuit for ECG acquisitionfrom a single lead. The acquisition circuit uses clip-type flat metal plate limb electrodes to sense the heart signalsand a basic amplifier circuit is designed using JFET OP-AMP IC LF-353 with the required gain to suitably amplify thesignal. The amplified data fed into a computer using USB-6009 is then denoised, processed and displayed usingLabVIEW software. The developed ECG acquisition module is evaluated by visual comparison of simultaneouslyrecorded data acquired by the module with and by the MP-150 amplifier system from BIOPAC Systems Inc. Tests havebeen performed in the laboratory on several volunteers in the age group of 28-60 and the results were quiet satisfactory.
