Sudden cardiac arrest is a sudden and life-threatening event that results from a disruption in the heart’s electrical system. This disturbance hinders the heart’s pumping action, causing an immediate cessation of breathing, consciousness, and blood flow throughout the body. Employing rapid response measures, such as deploying a defibrillator or initiating CPR, can significantly improve the chances of survival until emergency medical services arrive. Recognizing the urgency and acting promptly are pivotal steps in defying the silence of sudden cardiac arrest, contributing to a greater likelihood of positive outcomes and sustained lives.
