Portable ECG Measurement Device based on MSP430 MCU

We design a portable measurement device which can monitor electrocardiograph (ECG) and analyze arrhythmia. It is small, light, lower power, and consists of two parts: the main system and the sub. The device gets ECG signals by the electrode sticking to the chest skin. This make the device is suitable for monitoring in long time. 16-bits MCU-MSP430 is the most important part. Besides, there are amplifier circuit, filter circuit, wireless transmitting-receive circuit, data management part, keyboard and LCD display part, etc. The device can detect QRS complex and analyze ECG signals in real-time. For the MIT-BIH database and actual persons, the accuracy of monitor reaches above 99 percent of the QRS complex of ambulatory ECG signals.
