A Portable ECG Monitor with Low Power Consumption and Small Size Based on AD8232 Chip

Abstract

This paper design a portable ECG monitor based on mobile phone. Using the single-lead heart rate monitor analog front-end of AD8232 chip produced by ADI co. Ltd., the monitor can measure human ECG signal and heart rate with only two electrode pads placed on chest, and display the ECG signal on the mobile phone via Bluetooth communication in real time. It also can simply measure the heart rate by touching the two electrodes of the monitor directly. The system has many functions like ECG signal analysis, heart rate counting, arrhythmia detection, signal playback, leads off detection, fast recovery ECG. The result shows that the portable ECG monitor is low cost, low power consumption, small size and easy to carry, etc.
