Which term is a condition in which the heart's electrical impulses are disorganized, preventing the heart muscle from contracting normally and pumping blood?

Which term is a condition in which the heart's electrical impulses are disorganized, preventing the heart muscle from contracting normally and pumping blood?

• A. Ventricular Fibrillation (VF)
• B. Myocardial Infarction
• C. Hypotension
• D. Convulsion

Answer: (A)

Disorganized electrical activity in the heart that prevents the ventricles from contracting in a coordinated way is ventricular fibrillation. In this condition, the signals in the ventricles go chaotic, so the heart quivers instead of producing a strong, pump-like squeeze. Because the ventricles aren’t contracting effectively, blood isn’t pumped to the rest of the body, which can lead to collapse and death if not treated immediately. This is an emergency that typically requires rapid defibrillation and CPR to restore a normal rhythm and blood flow. Myocardial infarction is a heart attack caused by a blockage that cuts off blood supply to heart muscle, leading to tissue damage, but it doesn’t describe chaotic electrical activity. Hypotension means low blood pressure, which can have many causes and is about blood flow force rather than a problem with the heart’s electrical rhythm. Convulsions are seizures arising from brain activity, not the heart’s electrical system.
