When it comes to monitoring the electrical activity of the heart, an electrocardiogram (ECG) is an important diagnostic tool. ECG electrodes play a vital role in this process, but what exactly are they and how do they work?
ECG electrodes are small, sticky patches that are placed in specific locations on the body to detect and transmit electrical signals generated by the heart. These signals are then recorded and analyzed to assess the heart rhythm and detect any abnormalities.
How do ECG electrodes work?
Electrocardiogram electrodes work by creating a connection between the skin and the electrocardiogram machine. They are usually made of conductive materials, such as silver/silver chloride or stainless steel, which can transmit electrical signals. When the electrodes are placed on the skin, they adhere firmly to ensure a stable connection. A conductive gel or adhesive at the bottom of the electrode helps to improve electrical conductivity and reduce the impedance between the skin and the electrode.
Electrocardiogram electrode type
1. Disposable electrodes: These are disposable electrodes commonly used in hospitals and clinics. They are cost-effective, easy to use and reduce the risk of cross-contamination.
2. Reusable electrodes: These electrodes are designed for a variety of uses and are made of durable materials. They require proper cleaning and maintenance to ensure accurate readings and longevity.
3. Wet electrode: The wet electrode uses a conductive gel to improve the electrical contact between the skin and the electrode. They are commonly used in situations where high-quality signals are required, such as during stress tests or exercise electrocardiograms.
4. Dry electrode: Dry electrode does not need conductive gel, which is more convenient to use. They are commonly used in dynamic monitoring devices or wearable ECG monitors.
