V-fib most commonly occurs during an acute heart attack or shortly thereafter. When heart muscle does not get enough blood flow, it can become electrically unstable and cause dangerous heart rhythms. A heart that has been damaged by a heart attack or other heart muscle damage is vulnerable to V-fib.

Ventricular fibrillation (sometimes called v-fib for short) is an arrhythmia, a malfunction of the heart’s normal pumping sequence . It is the most common deadly arrhythmia. When it happens, the lower chambers of your heart quiver or twitch instead of completely expanding and squeezing.

Emergency treatment for ventricular fibrillation includes cardiopulmonary resuscitation (CPR) and shocks to the heart with a device called an automated external defibrillator (AED) . Medications, implanted devices or surgery may be recommended to prevent episodes of ventricular fibrillation.
Read moreWhat is the preferred first treatment for ventricular fibrillation?
The first response to V-fib may be CPR . This will keep your blood moving to important organs. Defibrillation. This is an electrical shock that is delivered to your chest wall to restore normal rhythm.
Read moreHow does ventricular fibrillation change the ECG?
ECG features of ventricular fibrillation The ECG shows irregular waves with varying morphology and amplitude . No P-wave, QRS complex or T-wave can be seen. This is pathognomonic (unique) to ventricular fibrillation and must not be confused with any other arrhythmia.
