The Development of ECG and PPG Measurement Device

Article Preview

Abstract:

We design a portable measurement device which can simultaneously detect ECG (electrocardiograph) and PPG (photoplethysmograph pulse wave) signal, analyze arrhythmia and calculate SpO2 (oxygen saturation of blood). It consists of two parts: the main and the sub. Besides of the most important part MSP430 MCU, there are front-end amplifiers, filter circuit, Bluetooth module, data management module, keyboard and LCD display module, etc. The device can detect QRS complex and PPG signals in real time. For the Fantasia database and patients, the monitor can correctly judge the QRS complex of ECG signals and PPG signal.
