Real-Time ECG Monitoring System Based on FPGA

Existing remote monitoring systems are usually situated in a hospital off line and the cost of sending physiology data by computer is high and the data can only be used within one hospital. In this paper, a real-time electrocardiogram (ECG) monitoring system is proposed based on field programmable gate arrays (FPGA). The FPGA chip is taken as the central microprocessor and applies structured design on very high speed integrated circuit hardware description language (VHDL) to collect and transmit real-time ECG signals. The experiment shows that the ECG monitoring system has a good performance. The digital filtering and data compression arithmetics are also integrated in the FPGA chip. This monitoring system has the advantages of high integration density, powerful function, low cost and convenience to carry around.
