What condition is defined as a useless fluttering of the heart muscle?

• A. Cardiac Arrest
• B. Ventricular Fibrillation
• C. Atrial Fibrillation
• D. Heart Attack

Answer: (B)

Ventricular fibrillation is defined as a condition characterized by the rapid and ineffective quivering of the heart muscle, specifically in the ventricles. In this state, the heart cannot pump blood effectively, which can lead to a loss of consciousness and, if not treated immediately, can be fatal. It occurs when there is disorganized electrical activity in the heart, resulting in a chaotic rhythm that disrupts the effective functioning of the heart. This condition is especially critical because it can lead to cardiac arrest if prompt medical intervention is not provided. Understanding the distinction between this condition and others, such as atrial fibrillation, can be crucial in emergency situations and can impact the course of treatment. The other conditions listed, like cardiac arrest and heart attack, refer to different mechanisms and processes that affect the heart, while atrial fibrillation involves irregular heart rhythms but does not lead to the immediate and chaotic muscle contractions seen in ventricular fibrillation.
