Which rhythm can be described as rapid, irregular ventricular activity that requires immediate intervention to prevent arrest?

• A. Atrial Fibrillation
• B. Agonal Rhythm
• C. Ventricular Fibrillation
• D. Ventricular Tachycardia

Answer: (C)

When the heart’s ventricular activity is rapid and chaotic with no coordinated contraction, there is no effective blood flow. This is ventricular fibrillation, a life-threatening rhythm that demands immediate action to prevent cardiac arrest. On the monitor, it appears as a jagged, irregular waveform with no discernible QRS complexes or organized rhythm. The immediate steps are CPR and rapid defibrillation to try to reset the heart’s electrical activity and restore a perfusing rhythm. This differs from atrial fibrillation, which is irregular but originates in the atria and may not be rapidly fatal right away; agonal rhythm is slow and irregular, indicating near-death status rather than rapid chaotic ventilation, and ventricular tachycardia is fast but typically more organized; if there’s no pulse, it is treated similarly to VF, but its rhythm is not the same chaotic pattern.
