Ventricular Fibrillation
Ventricular Fibrillation
Treatment and Care Options
Ventricular fibrillation is a medical emergency. Immediate treatment must occur in a healthcare setting and typically involves electric cardioversion (defibrillation) via an AED or manual defibrillator to reset the heart's electrical rhythm. Supportive care includes managing underlying conditions, such as optimizing electrolyte levels, controlling blood pressure, and using antiarrhythmic medications to prevent future episodes. Lifestyle changes, including managing weight, quitting smoking, and following a heart-healthy diet, are crucial for long-term management.
What Causes this Condition?
Ventricular fibrillation occurs when the electrical signals that tell the heart to beat are chaotic and disorganized. These disruptions prevent the heart muscle from pumping blood effectively.
- Underlying heart disease (such as coronary artery disease or heart failure).
- Electrolyte imbalances (such as low potassium or high calcium).
- Stress on the heart (such as during intense exercise or emotional stress).
- Medications or substance use that affect heart rhythm.
