The normal range of ECG monitoring should show the following features：
1.Regular heart rhythm: The time between each contraction and relaxation should be the same.
2.P wave: The P wave represents atrial contraction, which should have a clear and regular shape under normal conditions.
3.QRS complex: The QRS complex represents ventricular muscle contraction, and its duration is usually 0.06 to 0.10 seconds.
4.ST segment and T wave: The ST segment and T wave reflect the process of ventricular repolarization (returning to the initial, and their shapes should also fall within the normal range.
If you undergo ECG monitoring and find that your results differ from these standards, it may be necessary to seek help from a professional doctor for more detailed and accurate interpretation.
