What is Ventricular Fibrillation?
Ventricular fibrillation (VF) is a life-threatening heart condition characterized by the rapid and ineffective twitching of the ventricles. It is a crucial part of the heart's electrical system, which regulates heartbeat and blood flow. In VF, the normal rhythm of the heart is disrupted, leading to erratic and chaotic electrical signals that prevent the heart from pumping blood efficiently.
Commonly triggered by heart disease, particularly coronary artery disease or a prior heart attack, VF can also be caused by electrolyte imbalances, medications, or other medical conditions. Symptoms may include sudden collapse, fainting, or seizures due to a lack of blood flow to vital organs.
Immediate medical attention is critical. Cardiopulmonary resuscitation (CPR) and defibrillation are the most effective treatments. AEDs (automated external defibrillators) can restore normal heart rhythm by delivering an electrical shock.
Men, particularly those with risk factors such as high blood pressure, cholesterol, or a family history of heart disease, are at a higher risk for VF. Regular check-ups and a healthy lifestyle are essential in reducing the risk of heart-related chronic conditions. Awareness of VF and its signs can save lives.
