A DESIGN OF PORTABLE HEART-RATE MONITORING SYSTEM
Telemedicine is producing a great impact in the monitoring of patients located in remote non-clinical environments such as homes, elder communities, gymnasiums, schools, remote military bases, ships, and rural area. A number of applications, ranging from data collection to chronic patient surveillance, and even to the control of therapeutic procedures, are being implemented in many parts of the world. As part of this growing trend, this paper explains the design of a portable heart-rate monitoring system. A prototype system consists of analog data acquisition and pre-processing module which has an EEPROM memory for recording heart-rate values and corresponding time sequences. This module connected to computer via serial data communication protocol. At the computer side, we use interface software which is enable to graphically display the recorded heart-rate values.
