Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1] This is followed by sudden cardiac death in the absence of treatment. [2]
Ventricular fibrillation and pulseless or sustained ventricular tachycardia are the most commonly recorded arrhythmias preceding cardiac arrest. These are rapid and erratic arrhythmias that alter the circulatory pathway such that adequate blood flow cannot be sustained and is inadequate to meet the body's needs.
Ventricular fibrillation was more easily induced in smaller, leaner animals. [1] The velocity of the impact by a hard object is a critical factor for the onset of commotio cordis: impacts at 40 miles per hour (64 kilometres per hour) were the most likely to cause ventricular fibrillation in an animal model. [1] At velocities of 20 miles per ...
The main cause of cardiac arrest is two types of arrhythmias called ventricular fibrillation or ventricular tachycardia. ... When heart arrest occurs outside of a hospital, the main treatment is a ...
When people experience ventricular fibrillation, the heart stops pumping and causes “full-blown cardiac arrest.” Ventricular fibrillation occurs in a lot of situations, such as heart attack ...
[5] [6] Larger currents can result in tissue damage and may trigger ventricular fibrillation or cardiac arrest. [7] If death results from an electric shock the cause of death is generally referred to as electrocution. Electric injury occurs upon contact of a body part with electricity that causes a sufficient current to pass through the person ...
Precordial thump is a medical procedure used in the treatment of ventricular fibrillation or pulseless ventricular tachycardia under certain conditions. The procedure has a very low success rate, but may be used in those with witnessed, monitored onset of one of the "shockable" cardiac rhythms if a defibrillator is not immediately available.
On the day of my husband’s cardiac arrest, many things had to go right for him to survive. As soon as my call went through, 911 dispatched first responders to our location, which wasn’t easy ...
