Final Answer:
Aortic valve stenosis is considered a mechanical failure of the heart that may lead to cardiac arrest.
The correct option is C.
Explanation:
Aortic valve stenosis is a mechanical issue of the heart where the aortic valve narrows, obstructing the blood flow from the heart to the aorta. This condition can lead to increased strain on the heart and potential cardiac complications, potentially resulting in cardiac arrest due to mechanical failure.
Asystole (A) is the absence of electrical activity in the heart, not a mechanical issue. Ventricular tachycardia (B) is a rapid heartbeat originating in the heart's lower chambers, often due to electrical abnormalities. Agonal breathing (D) is a type of irregular, gasping breathing pattern that occurs in some cardiac arrest cases, but it's not a mechanical failure of the heart.
So, the correct option is C) Aortic valve stenosis
