kammiovärinän

Kammiovärinän, also known as ventricular fibrillation (VF), is a life-threatening cardiac arrhythmia characterized by rapid, disorganized electrical activity in the ventricles of the heart. Instead of a coordinated contraction that pumps blood effectively, the ventricular muscle fibers quiver chaotically. This results in a severe reduction or complete cessation of blood circulation to the body and brain.

The most common cause of kammiovärinän is acute myocardial infarction (heart attack), where damage to the heart muscle disrupts its electrical pathways. Other potential causes include severe electrolyte imbalances, particularly potassium and magnesium abnormalities, genetic heart conditions like long QT syndrome, trauma to the chest, and certain drug toxicities.

Symptoms of kammiovärinän are sudden and dramatic. Individuals typically experience immediate loss of consciousness, no pulse, and absent breathing. Without prompt intervention, irreversible brain damage and death occur within minutes.

The diagnosis of kammiovärinän is made through an electrocardiogram (ECG), which shows a characteristic irregular, chaotic waveform with no discernible P waves, QRS complexes, or T waves. The immediate treatment for kammiovärinän is cardiopulmonary resuscitation (CPR) to maintain some blood flow and oxygenation to vital organs, followed by defibrillation. Defibrillation uses an electrical shock to reset the heart's electrical rhythm. Early recognition and intervention are critical for survival and improving neurological outcomes.
