Portable electrocardiographic monitor based on digital signal processor

The utility model relates to a portable electrocardiographic monitor based on a digital signal processor, which belongs to the technical field of a medical electronic apparatus. The utility model comprises digital signal processor, an A/D collector, an electrocardio amplifier, a D/A converter, an acoustic coupling transmission end connected with an output end of the D/A converter, a function button, a flash memory, an MODEM interface controller and a DC-DC direct current voltage output supply providing the electric power for the electrocardiographic monitor. The electrocardiographic monitor also comprises a software process program which is previously stored in the processor and a liquid crystal display connected with the microprocessor. Compared with the existing electrocardiogram monitor, the calculation speed of the utility model is enhanced near hundredfold. The monitor can accurately analyse and distinguish an electrocardio signal and can display the common cardiac arrhythmia; a monitoring analyzer can automatically make an audible alarm if the state of illness is serious. The electrocardiographic monitor uses a cabinet liquid crystal display, therefore, the user's operation is more convenient and simpler.
