Single-lead ECG acquisition system based on GD32F350

Traditional ECG monitoring commonly includes conventional ECG testing, monitoring ECG testing and dynamic ECG testing. Routine electrocardiogram testing uses 12-lead synchronous detection, and most of them are used in hospitals or physical examination centers. It has shortcomings such as large equipment size and unsuitable for out-of-hospital monitoring. Monitored ECG uses three leads to detect ECG signals. It mainly includes real-time ECG monitors in CCU and ICU care rooms. It is charged by the time and is limited to hospitals. The common ambulatory electrocardiogram test uses different numbers of electrodes to detect ECG signals from different leads. The equipment needs to be reserved in advance. Data analysis and report acquisition require going to the hospital, and it is not portable enough.

In order to monitor the heart rhythm characteristics of the human body more conveniently and efficiently, a single-lead ECG acquisition system based on GD32F350 was designed. The system uses a single-lead method to obtain ECG signals. Users only need to install the lead electrodes on their hands, and they can check their ECG anytime and anywhere without going to the hospital to specifically check their heart health. The system uses Bluetooth transmission method to upload the ECG signal to the mobile phone APP in real time through Bluetooth. The APP integrates the filtering algorithm of the ECG signal to draw the user's ECG in real time. At the same time, after the measurement is completed, a measurement report is given. This system not only solves the inconvenient problem of traditional ECG monitoring equipment, but also provides users with ECG analysis reports and ECGs, providing detailed reference for further diagnosis by doctors.
