With the lower chambers of your heart quivering (fibrillating), due to erratic signals, the heart is unable to pump any blood to the rest of your body.
Ventricular Fibrillation causes your blood pressure to drop very quickly, cutting off blood supply to your vital organs, leading to cardiac arrest (heart attack).
Main Causes Of Ventricular Fibrillation Include:
- Not enough blood flow to the heart muscle or damage to the heart muscle from a previous heart attack.
- Cardiomyopathy (chronic disease of the heart muscle)
- Problems with the Aorta (the upper chambers of the heart)
- Drug toxicity (poisoning)
- Sepsis (severe infection)
Conditions that increase your risk:
- A previous episode of Ventricular Fibrillation
- A previous heart attack
- A heart defect you’re born with (Congenital Heart Disease)
- Heart muscle disease (Cardiomyopathy)
- Injuries that cause damage to the heart muscle, such as electrocution
- Use of illegal drugs, such as Cocaine or Methamphetamine
- Electrolyte abnormalities, such as with potassium or magnesium
Early Signs And Symptoms:
Most cases of V. Fib start with Ventricular Tachycardia, a condition in which the lower chambers of your heart beat too fast.
➡ Signs and symptoms of Ventricular Tachycardia include:
- Chest pain
- Rapid heartbeat (tachycardia)
- Shortness of breath
- Loss of Consciousness
- The person will collapse within seconds. It’s the most frequent cause of sudden cardiac death.
- Emergency treatment includes cardiopulmonary resuscitation (CPR) and shocks to the heart with a device called a defibrillator. CALL 911.
- Treatments for those at risk of V. Fib include medications to regulate the heart rhythm and implantable devices that can restore a normal heart rhythm.
