Design of Miniaturized ECG Signal Detection System

In order to overcome the safety hazard of sudden heart disease,early detection and early treatment of heart disease,a miniature ECG signal detection system based on embedded microcontroller has been developed,which includes ECG signal acquisition hardware and control system software and heart rate conversion algorithm design to achieve the acquisition of the testee’s electrocardiogram,respiratory wave and heart rate,serial communication is used to upload to the serial screen display module,and a set of Qt host computer software based on ECG signal detection is designed. The system can realize the collection of ECG data and view the physiological and pathological status. The test result verification shows that the system can obtain the subject’s ECG and respiratory waveform under the conditions of ensuring high accuracy and low power consumption,and accordingly,it can accurately calculate and display the heart rate value.
