As a medical professional with expertise in cardiology, I can explain what it means to be in V fib. V fib, short for Ventricular Fibrillation, is a life-threatening medical emergency where the heart's ventricular chambers quiver chaotically instead of beating effectively. This condition prevents the heart from pumping blood effectively, leading to a lack of oxygen-rich blood being delivered to the body and brain. It is often a result of an underlying heart condition, but it can also be triggered by other factors such as electrolyte imbalances, certain medications, or drug overdoses. The treatment for V fib typically involves immediate defibrillation, which is the application of an electric shock to the heart to attempt to restore a normal heart rhythm. read more >>
