CONCEPT AND EXPLANATIONS: DEFIBRILLATION
In order for blood to circulate efficiently through the body, the heart’s myocardium and muscle fibers contract according to the electrical rates that have been ordered.
Cardiac arrest can occur at any time and in most cases without prior signs.
During a sudden cardiac arrest, the electrical impulses are disordered therefore no longer allowing the heart to function properly.
To restore this rhythm, defibrillation is necessary. Also known as external electric shock, defibrillation is the medical act of passing a short electrical circuit through the heart.
