Which condition is a common cause of ventricular fibrillation?

• A. Congestive heart failure
• B. Cardiac arrest
• C. Myocardial infarction
• D. Atherosclerosis

Answer: (C)

Ventricular fibrillation (VF) is a life-threatening heart rhythm that leads to ineffective quivering of the heart's ventricles, preventing normal blood circulation. Myocardial infarction, commonly known as a heart attack, is characterized by the interruption of blood flow to the heart muscle, usually due to a blockage in a coronary artery. This lack of blood supply can result in damage to the heart tissue, which increases the risk of developing abnormal electrical activity in the heart. During a myocardial infarction, the damaged heart muscle can become irritable and trigger chaotic electrical impulses, leading to ventricular fibrillation. The presence of scar tissue and ischemic conditions following a heart attack can significantly predispose an individual to this critical arrhythmia. Therefore, among the listed conditions, myocardial infarction stands out as a prevalent catalyst for ventricular fibrillation.
