The Design of Low Power Portable ECG Monitor

摘要

As an important means of observing cardiac information, ECG monitoring is used to reflect the current changes of heart rate in real time, and is an important basis for judging cardiovascular diseases. For the current medical ECG monitoring equipment, there are some problems that the instrument is too large, the operation is complicated, and the real-time monitoring cannot perform for a long time. This paper uses BMD101 chip to design a portable ECG monitoring node with small size, low power consumption and long-term real-time monitoring. The implementation method includes two steps. First, we used two electrodes to collect bioelectrical signals from the human body. Then, the BMD101 chip will amplify, filter and A/D convert this signal, and then use the corresponding algorithm to get the heart rate of the human body.
