[Research and Design of a System for Detecting Automated External Defbrillator Performance Parameters].

Objectives: In order to regularly detect the performance parameters of automated external defibrillator (AED), to make sure it is safe before using the instrument, research and design of a system for detecting automated external defibrillator performance parameters.

Methods: According to the research of the characteristics of its performance parameters, combing the STM32's stability and high speed with PWM modulation control, the system produces a variety of ECG normal and abnormal signals through the digital sampling methods.

Results: Completed the design of the hardware and software, formed a prototype.

Conclusions: This system can accurate detect automated external defibrillator discharge energy, synchronous defibrillation time, charging time and other key performance parameters.
