A Novel Pocket Intelligent One Lead ECG Monitor Based on Fingers Touching

In this paper, a Pocket Intelligent ECG One Lead Monitor (PIEOLM) is present, which can be used for detecting human Electrocardiogram (ECG). Advanced RISC Machines (ARM) as well as instrument amplifier, electrodes, Universal Serial Bus (USB) and Secure Digital Memory Card (SD) technologies are adopted in hardware design. In software frame, digital filter, correcting baseline drift, detecting R wave and cardiac arrhythmia analysis are used for ECG rendering. Users simply touch the electrodes by two fingers, his/her ECG tracing and heart rate is displayed alive on LCD. The heart rate is displayed with beep sound and LED flashing. The PIEOLM also can storage and transport data to PC through USB cable. An antitype of this device has been finally accomplished and will be put into the clinical environment. The results of the experiment show that this PIEOLM is clinically approbated, accurate in its estimation, easy-to use and light-weight.
