Abstract As one of the most commonly seen diagnostic tools in clinic, ECG has been applied in more and more fields. It has qualified to become one of the five major routine examinations(blood, urine, stool, imaging, ECG) at present. Especially on some cardiovascular diseases such as chronic ischemic heart disease, acute coronary syndrome, myocarditis, pericarditis, pulmonary embolism and arrhythmia, ECG could make a definite diagnosis. In addition, ECG also plays an important auxiliary role in the diagnosis of hereditary ion channel disease, cardiac structural abnormality, electrolyte disturbances, and so on. Meanwhile, the application of ECG also extends to monitor the curative effect of antiarrhythmic drugs and arrhythmic conditions, make preoperative risk evaluation, and screen the population with highrisk or special occupation. Therefore, to accurately record and analyze ECG is of great concern. With the rapid introduction of digital technology, the performance of digital electrocardiograph has been greatly improved. However, old model has not yet been completely out of the market, which haunts the normalized operation of ECG examination. Routine ECG examination should be performed by ECG related professional and technical personnel. Normalized operation is a prerequisite for acquiring quality qualified ECGs, and also lays a foundation for making correct ECG diagnosis. “Guidelines for the operation of routine ECG examination” is suitable for ECG related professional and technical personnel.
