WebThe Progression from V-Tach to Fine VF. Defibrillation is the definitive treatment for the life-threatening cardiac arrhythmias, ventricular fibrillation, and pulseless ventricular tachycardia. Defibrillation consists of delivering a therapeutic dose of electrical energy to the affected heart with a device called a defibrillator. WebVentricular fibrillation (VF) is considered the most serious cardiac arrhythmias. Disordered electrical activity causes the ventricles to quiver (or fibrillate) instead of contracting normally. This prevents the heart from pumping blood, causing collapse and cardiac arrest . VF has been identified in nearly 70% of cardiac arrest patients. com.apple.geod crash Ventricular tachycardia is a heart rhythm problem (arrhythmia) caused by irregular electrical signals in the lower chambers of the heart (ventricles). This condition may also be called V-tach or VT. A healthy heart typically beats about 60 to 100 times a minute at rest. In ventricular tachycardia, the heart beats faster, usually … See more When the heart beats too fast, it may not pump enough blood to the rest of the body.
