An electrocardiogram (ECG) is a medical device that detects the activity of the heart by recording the electrical signals emitted by the heart through electrodes and making an image of this signal that reflects the heart's pulse and rhythm. One such line, the isoelectric line, is a baseline reference line on the ECG that represents the zero-potential state, the level that would be present in the absence of an electrical signal from the heart. The isoelectric line can help doctors better determine the heart's rhythm and the presence of abnormalities.
The isoelectric line is also an important indicator of heart health on an ECG, not only for detecting abnormalities in the heart's rhythm, but also for detecting myocardial ischemia, hypoxia, and other pathologies. In general, isoelectric lines should be flat in a normal person, and if there is a significant rise or fall, there may be a heart problem. Therefore, the role of isoelectric lines is widely used in the medical field as a basis for diagnosing heart disease.
In short, the position of the isoelectric line in the ECG is very important, it is the reference line for the heart's electrical signals, which can help doctors better determine the health of the heart. When performing an ECG, the doctor will make adjustments to the isoelectric wire to ensure that it is positioned correctly with the electrodes affixed to it. Therefore, it is important for the person undergoing the EKG to remain relaxed and not move to help the doctor obtain more accurate EKG data.
