APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart. Although not fully understood, this process depolarizes a large amount of the heart muscle, ending the arrhythmia.

Detailed explanation-2: -Also known as electrical cardioversion, defibrillation is most effective when a healthcare provider delivers the shock as soon as possible after an arrhythmia starts.

Detailed explanation-3: -Electrodes are the components through which the defibrillator collects information for rhythm analysis and delivers energy to the patient’s heart. Many types of electrodes are available including hand-held paddles, internal paddles, and self-adhesive disposable electrodes.
