The length and width of each cell on the ECG chart are 1 mm, in which the horizontal line represents time and the vertical line represents voltage.
Generally, the speed of paper feeding is 25 mm per second, each small grid on the horizontal line represents 0.04 seconds, and generally a small vertical grid represents a voltage of 0.1 millivolts.
The role of the electrocardiogram
Electrocardiogram is the standard for detecting arrhythmia diseases, and arrhythmia diseases include atrial tachycardia, ventricular tachycardia, supraventricular tachycardia, pre-excitation syndrome, etc. Electrocardiogram is also used for physical examination of various groups of people .
When the patient undergoes an ECG examination, the mood and surrounding environment should be kept in a quiet and stable state, and the patient should be allowed to fully expose the wrist, ankle or chest, and at the same time avoid talking. If the patient is too thin, you can apply gel or oil on the chest. Ordinary patients can moisten the chest with water. If you have had an electrocardiogram before, you should bring the previous electrocardiogram report for comparison. If the patient takes an overdose of drugs that may affect the heart rate or affect the electrocardiogram, the doctor should be informed of the drugs and their doses to avoid misdiagnosis. It is also necessary to avoid eating spicy and greasy food before the examination, such as chili, pepper or fatty meat.
