Introduction
Ventricular fibrillation can lead to death if not promptly treated within 4 to 6 minutes. It is a severe type of arrhythmia; when it occurs, the ventricles lose their ability to contract and are instead replaced by uncoordinated and rapid twitching, resulting in the heart's inability to pump blood. On auscultation, heart sounds are clearly absent.

Ventricular fibrillation is a severe type of arrhythmia. When it occurs, the ventricles lose their ability to contract and are instead replaced by uncoordinated, rapid twitching, rendering the heart incapable of pumping blood. Upon auscultation, heart sounds will be clearly absent. Ventricular fibrillation significantly disrupts blood flow and is equivalent to cardiac standstill, making it one of the most fatal arrhythmias, often resulting in death within a short time. Various factors can trigger ventricular fibrillation, including myocardial infarction, severe hyperkalemia, or hypokalemia. Immediate resuscitation measures such as chest compressions or electrical defibrillation must be administered promptly after onset to help maintain cerebral perfusion.
During this period, it's essential to keep the patient calm and avoid excessive anxiety. The patient should remain lying flat, preferably on a firm surface such as a bed board or the floor. Avoid performing random compressions or rescue attempts, which could lead to improper procedures.
