Low Cost Portable ECG Data Acquisition System.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
A design strategy for the data acquisition block of a portable ECG machine for affordable remote
CVD detection and diagnosis is proposed. It exploits the ECG property that most of the signal
is concentrated within 20 Hz. Using this system one can achieve a low Nyquist data rate of 50
samples/sec. With Data Acquisition System designed one can also perform Irregular Sampling and
using Compressive Sensing recover the signal. Using three such boards 3 ECG leads were simultaneously
sampled both using Nyquist sampling and Irregular sampling. The cost of the one single
board comes to Rs. (83+300) 383 and that of 3-Lead to Rs. (249 +500) 749. The Microcontroller
board cost is not included as it was given free of cost.
