Notes on use:
1. Confirm that the leads are connected to the limbs correctly and the electrical performance is good.
2. When doing ECG, if the amplitude exceeds the range of the ECG chart and the heart rate is too slow or too fast, adjust the voltage and paper speed to a reasonable range in time.
3. When a patient with agitation takes an electrocardiogram, the family will assist in the electrocardiogram, and use manual mode to perform lead-by-lead tracing step by step.
4. During the ECG examination, if abnormal changes (acute changes) are found in the special ECG, you should contact the clinician in time and limit the patient's activities. After the ECG is done, the patient information (including name, age, time) should be recorded and pasted in time.
5. After tracing the conventional twelve-lead electrocardiogram, if there is an abnormal Q wave in lead III (that is, the Q wave is greater than 1∕4R wave), an inspiratory tracing should be added. If the R wave in leads V1 and V2 is high, or if posterior myocardial infarction is suspected, lead V7-V9 should be added; if right ventricular infarction is suspected, lead V3-V6R should be added.
6. If you cannot handle the emergency, you should contact the superior teacher in time to ensure medical safety.
