In this project an ECG measurement and wave identification system was made. The measuring system hardware is based on a Texas Instruments ADS1298ECG amplifier and analog-to-digital converter board. The measurement and processing software was created in LabVIEW environment using the built-in functions of the Biomedical toolkit. Initially, the theory behind heartbeat and its effect on the skin surface potential are presented. Then the measurement techniques of these are described. The research group provide information on the mathematical background of how the ECG curve is processed and the waves are identified. The HRV analysis, the statistical analysis of identified R waves are described. Subsequently, publications dealing with electrocardiographic examinations in various fields will be presented. Then an overview of the specifications of the amplifiers used in this work and the capabilities of their original software are given. The final device structure is presented. The system validation process and the properties of the reference devices are illustrated. [ABSTRACT FROM AUTHOR]

Abstract: A 12-lead ECG data acquisition system based on ADS1298 is presented in this paper. ADS1298 is a latest 16-channel 24-bit Analog to Digital Converter (ADC) made in TI Company, which has the characters of high-precision, low power and low noise, with the internal integration of the input multiplexers, analog low-pass filter, and digital filter, etc. Combined with the high-speed low-power chip M051 as MCU, it can achieve the standard 12-lead simultaneous ECG acquisition. ECG data can also be transmitted to an upper host PC though nRF24LE1 MCU. This system greatly compact the circuit and reduce the power cost, as well as implement the wireless transmission. It has laid the foundation for the future high-accuracy portable ECG instrument. [Copyright &y& Elsevier]
