What does the term 'ventricular fibrillation' refer to?

• A. A heart that is not beating
• B. An irregular heartbeat
• C. A chaotic electrical activity of the heart
• D. The heart rate exceeding 100 beats per minute

Answer: (C)

Ventricular fibrillation refers to a chaotic electrical activity of the heart, which is a critical and life-threatening arrhythmia. In this condition, the electrical signals in the ventricles become disorganized, causing the heart to quiver instead of contracting effectively. This results in the heart being unable to pump blood, which can lead to sudden cardiac arrest if not treated promptly. The chaotic nature of the electrical activity means that the heart cannot maintain a consistent rhythm necessary for effective blood circulation, making immediate medical intervention essential. Understanding this concept is crucial for recognizing the signs of cardiac emergencies and responding appropriately.
