Abstract

The paper describes a comprehensive system - a digital phonocardiogram (PCG) analyzer, which can acquire heart sounds and electrocardiogram (ECG) in parallel, synchronize the display and play of heart sounds and unite auscultation and check phonocardiogram. The hardware which controlled by MCU C8051 F340, acquires heart sounds and ECG synchronously, and then sends them to indicators, respectively. Heat sounds are displayed and played simultaneously by controlling the moment of writing to indicator and sound output device. In clinical test, heat sound can be successfully located with ECG and real-time played.
