Cardiac arrest is sudden, but survival hinges on quick action
Ventricular fibrillation and tachycardia are the key culprits in sudden cardiac arrest. Without CPR or defibrillation, survival drops 10% each minute. Understanding risk factors, from hypertrophic cardiomyopathy to electrolyte imbalances, can empower earlier screening and intervention. Rapid pre-hospital care remains the most critical determinant of survival.
