Which condition is defined as sudden stoppage of heart action often leading to sudden cardiac death?

• A. Bradycardia
• B. Dyspepsia
• C. Cardiomyopathy
• D. Cardiac arrest

Answer: (D)

The rapid, complete halt of heart activity that stops blood flow is the key idea. Cardiac arrest is when the heart suddenly stops pumping effectively due to an electrical disturbance, so the person collapses, loses consciousness, has no pulse, and isn’t breathing normally. Without immediate CPR and defibrillation if appropriate, this can quickly lead to death, which is why it’s described as sudden cardiac death in many cases. Bradycardia is simply a slow heart rate, which may still allow some blood flow; dyspepsia is indigestion and unrelated to heart function; cardiomyopathy is a disease of the heart muscle that can weaken the heart or cause rhythm problems but does not by itself define an abrupt stop in heart action.
