What characterizes ventricular fibrillation?

Ventricular fibrillation is characterized by a continuous, uncoordinated, chaotic rhythm within the heart's ventricles. This erratic electrical activity prevents the heart from effectively pumping blood, leading to a lack of circulation. Unlike a rapid, consistent heart rhythm or an organized rhythm that produces pulses, ventricular fibrillation results in a disorganized pattern that disrupts the normal cardiac cycle. Consequently, the heart fails to generate any measurable blood pressure or pulses, making it a life-threatening condition that necessitates immediate medical intervention. Understanding this chaotic nature of ventricular fibrillation is crucial for recognizing its symptoms and effectively responding in emergency situations.
