V Fib is characterized by?

• A. Organized rhythm
• B. Regular rhythm
• C. Disorganized rhythm
• D. Normal sinus rhythm

Answer: (C)

Ventricular fibrillation is characterized by disorganized electrical activity in the ventricles, producing no coordinated contraction and no effective cardiac output. On an ECG this appears as chaotic, rapid, irregular waveforms with no recognizable P waves or QRS complexes, and the amplitude can vary unpredictably. Clinically, this means the patient has no pulse and is unresponsive, requiring immediate CPR and defibrillation to restore a perfusing rhythm. In contrast, an organized rhythm would show a pattern you can follow (such as regular beats or identifiable QRS complexes), a regular rhythm means evenly spaced beats, and normal sinus rhythm includes orderly P waves before each QRS and a normal rate.
