Development of a State-of-the-Art ECG DAS for Storing, Processing and Analysis Using MATLAB-Based GUI and Microprocessor

This paper illustrates a low cost novel method for ECG signal acquisition, display and storage using a Graphical User Interface (GUI), which provides a user-friendly front end by using MATLAB-based toolsets. At first, analog ECG has been converted to its digital equivalent with the help of an ADC. Microcontrollers converted this data to a serial (RS232) format and transmit to the PC for serial acquisition. The developed GUI performs the acquisition for its future processing.
