➡️Ventricular Fibrillation (V-fib)
Ventricular fibrillation is triggered when a problem in the heart's electrical system causes disorganized electrical signals to be sent across the ventricles. Instead of a coordinated, rhythmic contraction, the ventricular muscle fibers twitch randomly and out of sync. This results in a fast and irregular heart rhythm, which can be fatal if not treated immediately.

V-fib is considered a medical emergency because it can lead to sudden cardiac arrest and death. It is the most frequent cause of sudden cardiac death, with individuals often having no warning signs. If V-fib occurs, the individual will collapse within seconds and won't have a pulse.

➡️ Several factors increase the risk of developing V-fib, including:
- Previous heart attack
- History of heart disease
- Specific changes in heart structure
- Certain heart medications
- Stimulant or drug misuse

Other conditions such as hypoxemia, sepsis, hypothermia, or severe electrolyte imbalances can also predispose an individual to this arrhythmia. Ventricular fibrillation is confirmed with an electrocardiogram (ECG), which provides a recording of the heart's electrical activity. Emergency treatment aims to restore the heart's normal rhythm and involves cardiopulmonary resuscitation (CPR), defibrillation, and administration of certain medications. Defibrillation is required for this arrhythmia and involves sending an unsynchronized shock to the patient's heart. Remember that defibrillation is always recommended for life-threatening arrhythmias, including:

For those at a high risk of V-fib, preventative measures might include medication to control the heart rhythm or a device implant, like an implantable cardioverter-defibrillator (ICD), which continuously monitors the heart rhythm and delivers electric shocks if necessary to control arrhythmias. Ventricular fibrillation is a severe, life-threatening cardiac condition resulting from disorganized electrical activity in the heart's ventricles. It requires immediate medical attention, and if left untreated, it often leads to sudden cardiac death. Nonetheless, with rapid response and proper medical care, many people survive V-fib and can live healthy lives with appropriate treatment and management.
