Ventricular fibrillation (VF) is the primary rhythm of cardiac arrest that can lead to shock. Prolonged ventricular fibrillation leads to a decrease in waveform amplitude from initially coarse to fine VF and eventually degenerates into asystole due to the progressive depletion of myocardial energy reserves.
Causes of ventricular fibrillation
- Insufficient blood supply to the heart muscle.
- Damage to the heart muscle (for example, from a heart ■■■■■■)
- Problems with the aorta.
- Toxicity of the drug.
- Sepsis (severe body infection)
Both images show what ventricular fibrillation looks like on an ECG rhythm strip. VF can rapidly lead to myocardial ischaemia and there is a high likelihood of it progressing to asystole. Ventricular fibrillation is always pulseless and must be confirmed by an ECG monitor or defibrillator.
Ventricular fibrillation (Vfib or VF) occurs when the heart trembles instead of pumping due to disorganized electrical activity in the ventricles. It’s a kind of heart rhythm disorder.
The survival rate of ventricular fibrillation (VF) is up to ten times that of other cardiac arrest rhythms. The incidence of VF at the time of cardiac arrest is estimated to be 6070% in all patients and 8085% in probable heart disease.
Sometimes the TV can take less than 30 seconds (not overhauled) and cause no symptoms. But watching TV can be a sign of serious heart problems. If the TV lasts longer than 30 seconds, it usually leads to palpitations, dizziness or fainting.
Although both atrial fibrillation and ventricular fibrillation can cause serious medical problems in a patient. Ventricular fibrillation, especially if it persists, is considered to be much more serious as the patient can experience sudden ■■■■■ or cardiac arrest and die quickly.
Stress can cause heart attacks, sudden cardiac ■■■■■, heart failure, or arrhythmias (abnormal heart rhythms) in people who may not even know they have heart disease. Lower threshold for abnormal heart rhythms, including ventricular tachycardia, ventricular fibrillation, and atrial fibrillation.
Ventricular fibrillation (VF) is a condition in which the heart beats at an abnormal rhythm. Your heart should beat regularly and regularly. VF makes the heart beat fast and rhythmically. This is an emergency that can occur during a heart ■■■■■■.
Atrial fibrillation occurs in the two upper chambers of the heart, called the atria. Ventricular fibrillation occurs in the two lower chambers of the heart, called the ventricles. Although they have similar names and are both found in the heart, AFib and VFib affect the body in different ways.
One major difference between these two heart conditions is that ventricular fibrillation is life-threatening if treatment is not started immediately, while atrial fibrillation is usually not immediately life-threatening but can lead to serious complications if left untreated. .
These complications may or may not be toxic or specific in heart patients and may also occur with other medications: vasodilators and antianginal drugs (lidoflazine, vinamine, fenoxedil), psychotropic drugs (phenothiazine and imipramine), antimitotics, antimalarials (chloroquine) or antibiotics (
Ventricular fibrillation rarely ends spontaneously, as different wave fronts such as reentry coexist independently of each other and simultaneous extinction of all circuits is unlikely.
There are a number of inherited diseases that can cause irregular heartbeat and sudden cardiac ■■■■■. Some of them are very rare. The most common are: Brugada syndrome: a genetic heart rhythm disease that can lead to ventricular fibrillation and sudden cardiac arrest.
It’s possible. Hereditary atrial fibrillation is called familial atrial fibrillation. Although the exact incidence of familial atrial fibrillation is unknown, recent studies suggest that up to 30% of people with atrial fibrillation may have a relative with the disease.
