Defibrillators are critical medical devices designed to correct life-threatening cardiac arrhythmias, particularly ventricular fibrillation and ventricular tachycardia, which can rapidly lead to sudden cardiac arrest (SCA). By delivering a controlled electrical shock to the heart, defibrillators aim to restore a normal cardiac rhythm and prevent irreversible organ damage or death. According to the World Health Organization (WHO), cardiovascular diseases remain the leading cause of mortality globally, accounting for nearly 17.9 million deaths annually, with sudden cardiac arrest being a major contributor within this burden. Early access to defibrillation is therefore r...
