VF primarily means Ventricular Fibrillation, a life-threatening heart condition where the heart quivers instead of pumping blood, requiring immediate CPR and defibrillation. It also has meanings in other fields, such as Video Frequency, Visual Field, Voice Frequency, Forward Voltage (electronics), or Version Française (French-dubbed media).
Ventricular fibrillation is an emergency that requires immediate medical attention. It's the most frequent cause of sudden cardiac death.
Ventricular fibrillation, or VF, is considered the most serious abnormal heart rhythm. VF is extremely dangerous and can lead to sudden cardiac death.
First call 911 or your local emergency number. Then start CPR by pushing hard and fast on the person's chest — about 100 to 120 compressions a minute. Let the chest rise completely between compressions. Continue CPR until an automated external defibrillator (AED) is available or emergency medical help arrives.
Fast (type I) VF is associated with a steep APD restitution, normal excitability with a flat CT−1 restitution, and wandering wavelets. Slow (type II) VF is associated with a flat APD restitution, low excitability with a steep CT−1 restitution, and spatiotemporal periodicity.
The most common precipitating factors include acute myocardial infarction, ischemic cardiomyopathy, severe electrolyte disturbances, drug toxicity, and structural heart disease.
Ventricular fibrillation (VF) is the most important shockable cardiac arrest rhythm. It is invariably fatal unless advanced life support is rapidly instituted.
CPR and defibrillation can restore your heart to its normal rhythm and may be lifesaving. Medicines and certain procedures after an episode of ventricular fibrillation can prevent or reduce the chances of another episode. An ICD can promptly treat V-fib.
Since heart attacks are the top cause of ventricular fibrillation, preventing a heart attack can prevent v-fib, as well. You can do this by making lifestyle changes like: Eating heart-healthy foods. Getting regular physical activity.
In acute ventricular fibrillation (VF), drugs (eg, epinephrine, amiodarone) are used after three defibrillation attempts are performed to restore normal rhythm.
The chance of survival from ventricular fibrillation (VF) is up to ten times higher than those with other cardiac arrest rhythms.
Ventricular fibrillation and consciousness are not mutually exclusive. Recently, we witnessed two cardiac arrests in patients who remained conscious enough to deter resuscitation despite being pulseless with ventricular fibrillation.
Excessive stress can affect both frequency of arrhythmias as well as the impact of ventricular fibrillation (14).
Very Fine (VF) condition
A VF copy has minor defects, but is in overall excellent condition. Most well-kept modern comics (especially if they have been read) fall into this grade.
Ventricular fibrillation (VF) is a life threatening arrhythmia. Coarse VF and fine VF refer to the type of waves that appear on an EKG. If VF continues, coarse VF may deteriorate to fine VF, which may have a more negative outcome. People will require immediate defibrillation for both types of VF.
Ventricular fibrillation, also known as VFib, is a serious type of heart rhythm disorder that involves the heart quivering or twitching. The heart can't pump blood to the rest of the body, which leads to sudden cardiac arrest . Without lifesaving care, ventricular fibrillation can be fatal.
Ventricular fibrillation symptoms
Symptoms of Ventricular Fibrillation
Ventricular fibrillation causes unconsciousness in seconds. If untreated, the person usually has a brief seizure and then becomes limp and unresponsive. People develop irreversible brain damage after about 5 minutes because oxygen no longer reaches the brain. Death soon follows.
Hydration's Role in the Heart
Water helps the blood carry oxygen and nutrients to your cells while removing waste products. Without enough water, your heart must work harder, and your blood circulation may not be as efficient. When the heart works harder, the risk for Afib increases.
6 Tips for Restoring Your Heart Rhythm
Rarely, clinical examinations fail to identify an underlying cause and VF is classified as idiopathic [1], [2], [3]. Idiopathic ventricular fibrillation (IVF) is a diagnosis by exclusion, with a likely complex etiology, although in some cases it may have a strong genetic basis.
Ventricular fibrillation surgery and other therapies
For long-term prevention of ventricular fibrillation, the most common treatment is an implantable cardioverter-defibrillator (ICD). An ICD is a small device placed inside your body that monitors your heart's rhythm.
The 30-second rule in atrial fibrillation (AFib) is a widely used, though debated, guideline defining an AFib episode as an irregularly irregular heart rhythm lasting at least 30 seconds on an ECG, used to distinguish it from shorter, less significant atrial arrhythmias and help guide diagnosis and treatment, particularly for stroke risk and ablation success. While a standard for trials and device monitoring, newer research suggests shorter runs of AF might still be clinically important, prompting ongoing discussion about whether this threshold accurately reflects stroke risk and overall AF burden.
Idiopathic ventricular fibrillation occurs with a reputed incidence of approximately 1% of all cases of out-of-hospital arrest, as well as 3–9% of the cases of ventricular fibrillation unrelated to myocardial infarction, and 14% of all ventricular fibrillation resuscitations in patients under the age of 40.
