The plate exercise ECG is actually an exercise load test for ECG. The physician assesses the suitability for the exercise test and can connect the patient to ECG monitoring according to the standard 12-lead ECG monitoring standard site. After the patient stands on the exercise plate, the physician enters the patient’s personal information and starts the plate, initiating a level of exercise at a uniform speed and without slope, gradually increasing the amount of exercise through 3 minutes. Based on the patient’s symptoms, expression, gait and physical condition, the physician determines the duration of exercise and the maximum amount of work to be performed. If the heart rate reaches the individualized maximum target heart rate for age, sex, height, weight and race, and the exercise oxygen consumption reaches the maximum, individual maximum work, the physician will promptly terminate the planking exercise and give a negative assessment of the test results. The conclusion report of the plate exercise experiment will be written negative or positive, the so-called negative is in the process of exercise to reach the individualized maximum heart rate target value, as well as the maximum work done, the patient does not appear myocardial ischemic performance, indicating that the patient’s coronary reserve function is better. If it is positive, it means that there is a significant downward shift of ST segment during exercise and there are uncomfortable symptoms such as chest pain, dizziness and panic. It indicates that the patient has stenosis in the coronary vessels, which affects the exercise function. There is another kind of ST-T change is that the patient has no symptoms secondary to the original ST-segment change, and there will be a significant downward shift and deepening. This situation should be analyzed whether it is a secondary ST-T change or a non-specific ST-T change, which does not indicate the existence of stenosis in the patient’s coronary arteries and needs to be analyzed in conjunction with clinical analysis.
