Fibrillation can happen in either the atrial or the ventricles. When fibrillation happens in the ventricle it is usually immediately be life threatening. Which ECG below do you think shows ventricular fibrillation?

Verified step by step guidance1
Understand the characteristics of ventricular fibrillation on an ECG. Ventricular fibrillation is characterized by rapid, erratic electrical impulses in the ventricles, leading to a chaotic and irregular ECG pattern without distinct QRS complexes.
Examine each ECG image provided. Look for the presence of chaotic, irregular waveforms that lack the typical P wave, QRS complex, and T wave structure.
In the first ECG image, observe the presence of regular QRS complexes and P waves, indicating a normal or slightly irregular rhythm, not ventricular fibrillation.
In the second ECG image, note the presence of regular QRS complexes and P waves, suggesting a normal rhythm, not ventricular fibrillation.
In the third ECG image, identify the chaotic and irregular waveforms without distinct QRS complexes, which is indicative of ventricular fibrillation. This pattern is consistent with the life-threatening nature of ventricular fibrillation.
