As a cardiac specialist with extensive experience in the field of cardiology, I can explain why ventricular fibrillation is considered a life-threatening condition. Ventricular fibrillation (VF) is a type of cardiac arrhythmia characterized by rapid, irregular electrical impulses in the ventricles of the heart. These impulses cause the ventricles to contract in a disorganized and ineffective manner, which leads to a near-instantaneous cessation of effective blood circulation. The heart's inability to pump blood effectively means that the brain and other vital organs are deprived of the oxygen and nutrients they need to function. This deprivation can lead to unconsciousness within seconds and brain damage or death within minutes if not treated promptly. The reason VF is so dangerous is that it is often a sudden and unexpected event, especially in cases of coronary artery disease or other underlying heart conditions. It can also occur in individuals with no known heart problems, making it difficult to predict and prevent. Immediate medical intervention, such as defibrillation, is crucial to restore a normal heart rhythm and increase the chances of survival. read more >>

Ventricular fibrillation is more serious than atrial fibrillation. Ventricular fibrillation frequently results in loss of consciousness and death, because ventricular arrhythmias are more likely to interrupt the pumping of blood, or undermine the heart's ability to supply the body with oxygen-rich blood.read more >>
