Which condition is characterized by the ventricles quivering asynchronously?

• A. Atrial flutter
• B. Ventricular tachycardia
• C. Ventricular fibrillation
• D. Normal sinus rhythm

Answer: (C)

Ventricular fibrillation is characterized by the ventricles quivering asynchronously. This condition arises when the electrical signals in the ventricles become chaotic, resulting in ineffective contractions that prevent the heart from pumping blood adequately. Instead of the ventricles contracting in a coordinated manner, they experience rapid, disorganized impulses, which leads to a failure in maintaining an effective heartbeat. This lack of coordination can be life-threatening as it results in a complete absence of blood flow to vital organs, leading to rapid onset of unconsciousness and requires immediate medical intervention. Understanding this condition is crucial for recognizing life-threatening arrhythmias and the importance of defibrillation in restoring a normal rhythm. In contrast, conditions such as atrial flutter involve the atria rather than the ventricles, and while ventricular tachycardia involves fast, rhythmic beats originating from the ventricles, it does not exhibit the chaotic quivering seen in fibrillation. Normal sinus rhythm indicates a regular, coordinated heartbeat and is the standard for a healthy heart function.
