What does ventricular fibrillation (VF) typically appear as on an EKG?

Ventricular fibrillation (VF) is characterized by the heart's electrical activity becoming disorganized, which leads to the heart's ability to pump blood effectively being severely impaired. On an EKG, this is represented by chaotic, irregular waveforms. These waveforms do not have a consistent pattern, and there are no identifiable QRS complexes, P waves, or T waves, which are typically seen in normal sinus rhythm.

The appearance of chaotic, irregular waveforms on the EKG indicates that the heart is quivering rather than contracting effectively. This condition is life-threatening and requires immediate medical intervention to restore a normal rhythm. Recognizing this pattern is crucial for healthcare professionals who need to act quickly to stabilize the patient.
