The so-called ECG electrode is actually a sensor that is connected to the body surface and used to monitor the ECG signal.
The disposable ECG electrodes are silver and silver chloride electrodes, which are composed of a gas permeable paper substrate, a conductive paste, a silver/silver chloride electrode core, a medical grade pressure sensitive adhesive, a PET cover sheet, and a copper buckle.
ECG electrodes are mainly used in conjunction with Holter diagnostics or ECG monitoring instruments. ECG monitoring can reflect the working state of the heart by detecting changes in the potential difference (ie, lead) between the two points on the body surface of the human body. .
Ordinary ECG can only be used to simply observe the ECG activity during a short period of time when the ECG was recorded. The ECG monitoring is a non-invasive monitoring method for continuously monitoring the electrical activity of the heart through the display screen. It can observe the condition in time, provide reliable and valuable indicators of ECG activity, and guide real-time processing. Patients with abnormal activities, such as acute myocardial infarction, various arrhythmias, etc. have important value in use.
ECG monitoring is available for:
1. Cardiopulmonary resuscitation
It can help analyze the causes of cardiac arrest during cardiopulmonary resuscitation and guide treatment (such as defibrillation), and detect heart rhythm and heart rate changes.
2, high risk patients with heart rhythm disorders
Effective disease may develop a fatal heart rhythm disorder during development, so it is necessary to observe with ECG monitoring.
3, critical illness ECG monitoring
Some patients with acute myocardial infarction, myocarditis, cardiomyopathy, heart failure, cardiogenic shock, severe infection, pre-excitation syndrome, etc. also need ECG monitoring to avoid accidents.
4. Certain diagnostic and therapeutic operations
In the operation of tracheal intubation, cardiac catheterization, pericardial puncture, etc., rhythm disorder may cause sudden death, so the hospitals with conditions will be equipped with ECG monitoring equipment. In this process, ECG electrodes are also used as supporting equipment.
