Fibrillation ventriculaire

Overview 

Ventricular Fibrillation Disease is a life-threatening heart rhythm disorder (arrhythmia) in which the heart’s lower chambers (ventricles) quiver instead of pumping blood effectively. This leads to a sudden loss of blood circulation and can result in cardiac arrest if not treated immediately.

It is a medical emergency requiring urgent intervention such as defibrillation (electric shock) to restore a normal heart rhythm. Prompt treatment is critical to save life and prevent brain damage.

Types of Ventricular Fibrillation

• Primary Ventricular Fibrillation: Occurs suddenly without prior symptoms
• Secondary Ventricular Fibrillation: Develops due to underlying heart disease
• Paroxysmal Ventricular Fibrillation: Intermittent episodes of abnormal rhythm

Symptoms of Ventricular Fibrillation

• Sudden collapse
• Loss of consciousness
• No pulse
• No breathing
• Severe chest pain (before collapse in some cases)
• Dizziness or fainting

Causes of Ventricular Fibrillation

• Coronary artery disease
• Heart attack (myocardial infarction)
• Cardiomyopathy
• Electrolyte imbalance
• Heart valve disorders
• Congenital heart abnormalities
• Electric shock
• Drug toxicity

Complications of Ventricular Fibrillation

• Cardiac arrest
• Brain damage due to lack of oxygen
• Organ failure
• Death if untreated
• Long-term neurological damage

Risk Factors of Ventricular Fibrillation

• History of heart disease
• Previous heart attack
• Family history of sudden cardiac death
• Electrolyte imbalance
• Smoking
• Drug abuse
• High blood pressure

Prevention of Ventricular Fibrillation

• Manage heart disease effectively
• Control blood pressure and cholesterol
• Avoid smoking and substance abuse
• Maintain a heart-healthy lifestyle
• Regular cardiac check-ups
• Follow prescribed medications
