RESUMO

The electrocardiogram represents the electrical activity of the heart and is one of the most performed tests in cardiologists offices. The high resolution electrocardiogram may show features of the ECG signal important to diagnosis and usually not presented by the conventional test. This work presents the design, development and construction of a system that enables the acquisition, high resolution quantization and USB connection. The designed system uses a data interface that allows connection with an Atmel AT91SAM7S256 ARM microcontroller to perform the tasks of control and communication. The analog and digital filters necessary to acquire the heart signal are also presented, also are presented the solutions used for communication between the ARM microcontroller and the Texas Instruments ADS1256 ADC via SPI channel.
