Prototipo de holter digital

Abstract:

The present work describes the principles, the design and the construction of a holter digital, which is an instrument that registers the cardiac waves for a long period of time and in this case it will store the information in memory, after the information is unloaded to a computer, in where the signal will be observed. It is composed of different blocks: a) acquisition of the cardiac signal, b) filter of the signal, c) amplification and DC displacement, d) digitalization, e) storage and f) transmission of the information to the PC through a serial port. By means of the use of a program the interface of the PC that will take the data through the serial port and to show it in the monitor.
