What is defibrillator diagram?

A defibrillator diagram illustrates the components and operation of a device used to treat life-threatening cardiac arrhythmias, such as ventricular fibrillation. It typically shows electrode pads placed on a patient’s chest, connected to the defibrillator unit. The device includes a power source, control panel, and display screen. The diagram highlights the path of electrical current delivered through the chest to restore normal heart rhythm. Labels may indicate key features like the energy selection button, analysis function, and shock button. Such diagrams help medical personnel and lay responders understand correct pad placement, device operation, and the sequence of delivering a controlled electric shock.
