Electrodes and Leads
The ability to record electrical currents is made possible via electrodes, which are conductive pads fastened to the skin. By examining numerous electrodes, an ECG lead—a graphical representation of the electrical activity of the heart—is produced. In other words, the electrical currents detected by various electrodes are analyzed to determine the value of each ECG lead. The 12-lead ECG, often known as a conventional ECG, is created by utilizing 10 electrodes and is known as a 10-lead ECG. The limb leads and chest leads make up the two sets of ECG leads that make up these 12 leads.
Electrocardiogram (ECG)
Our bodies are primarily made of fluids. Body fluids are crucial for the normal operation of our tissues and perform the crucial tasks of supplying nutrients to live cells and removing toxic toxins created by our systems. Other systems that facilitate these activities have been evolved by other organisms. However, complex creatures like humans need fluids like blood and lymph to carry out the mentioned functions.
