Cautions for dynamic electrocardiogram

In terms of clothing wear, women had better not wear bras. Men should wear loose clothes and pay attention not to sweat more. Otherwise, wet skin can easily cause short circuit between adjacent electrodes, and the result of the test is not correct. Ltd.

You can watch TV. But it's better not to go online, so as not to generate interference waves, resulting in irregular graphics, lack of diagnostic basis. No exposure to radiation or radioactive substances. For example, try to avoid using mobile phones, microwave ovens, semiconductor radios and so on.

The skin contact with the dynamic ECG recorder should be free from local infection and keep hygienic. Ltd.

Do not bathe during electrocardiogram, it is best not to do strenuous exercise during the test, in order to avoid sweating caused the instrument to fall off. After wearing the recorder, daily living should be the same as before wearing, should do appropriate exercise, but not the more intense the better, especially to avoid the intense exercise of both upper limbs, in order to reduce all kinds of EMG interference and artifacts. According to the condition and the purpose of examination, inpatients can walk slowly and go upstairs and downstairs, while those suspected of angina pectoris can choose more intense exercise which may induce the onset of the disease, so as to observe the relationship between exercise volume and myocardial ischemia, arrhythmia, for doctors'diagnosis and reference. However, those who are seriously ill should follow the doctor's instructions.

Take a bath one day before the examination and keep the skin clean and dry. The electrodes are attached to the skin of the forechest and connected with the recorder by wires. If the skin is wet, the contact between the electrodes and the skin is not good, even causing the electrodes to fall off. The subjects have to do it again. In clinic, some patients sweat heavily. The result is either that part of the electrodes fall off or that there are too many ECG interference waves to be analyzed.

Detailed registration of physical discomfort and exercise time within 24 hours can find out whether the ECG changes during this period, and provide a reliable basis for doctor's diagnosis and treatment.
