Abstract :
A portable ECG recorder using dynamic RAM as the recording medium has been developed. The dynamic RAM interface hardware which includes three types of communication mode, that is to a PC, a microcontroller (MCS-51) and an A/D subsystem (AD7821) with dynamic RAMs, is described. This technique opens a new path to the development of low cost, small size and large capacity long-term physiological data recorders.
