Description

technical field [0001] The invention belongs to the technical field of bioelectric electrode performance detection, in particular to a wearable electrocardiographic electrode performance evaluation test platform. Background technique [0002] ECG examination is a commonly used medical measure in disease diagnosis and rescue. Through the observation of ECG, various heart rate markets, ventricular atrial hypertrophy, myocardial infarction, myocardial ischemia and other diseases can be judged. ECG monitoring is a variety of monitoring rooms and clinical diagnosis and treatment. A widely used diagnostic tool under operating conditions. To achieve the purpose of ECG monitoring, in addition to having ECG monitoring equipment, it is also necessary to paste ECG electrodes on different parts of the patient's body to collect the patient's ECG signals, and the performance indicators of the ECG electrodes are related to the performance of the ECG. Check that the results are accurate. ...
