Which description best fits Stop heart?

• A. No symptoms, complete body shut down, no pulse
• B. Blue lips, chest not moving, Cyanotic
• C. Very fast pulse
• D. Dizziness

Answer: (A)

When the heart stops, circulation comes to a halt and life-sustaining functions quickly cease. The best description captures this abrupt loss of life signs: no symptoms in the sense of ongoing vital signs, a complete body shutdown, and no pulse. This reflects cardiac arrest, where blood is no longer being pumped, so the person loses pulse and ultimately stops breathing and moving. The other descriptions describe conditions that can occur with severe distress but don’t indicate the full cessation of heart function: cyanosis with a chest that isn’t moving can occur with breathing problems or reduced oxygenation but doesn’t prove the heart has stopped; a very fast pulse means the heart is still beating; dizziness is a symptom that can precede collapse, not the event of the heart ceasing to beat.
