Abstract: As a technical method to detect cardiomotility of human body, ECG monitoring is widely used in various clinical departments of hospital, as an important guarantee for disease diagnosis, patients saving and treatment. Therefore, the testing and management of the performance of ECG monitoring equipment is of great importance. In view of researches from the perspective of disposable ECG electrode performance testing, the study puts forward a design scheme of disposable ECG electrode tester, and confirms the effectiveness of the design for ECG electrode performance testing through the test of disposable ECG electrode.
