fibrillaatioiden

Fibrillaatioiden, often translated as fibrillation, refers to a type of abnormal heart rhythm characterized by rapid, uncoordinated, and irregular contractions of the heart muscle. Instead of a strong, regular beat, the cardiac chambers quiver inefficiently. This condition can affect either the atria (the upper chambers) or the ventricles (the lower chambers) of the heart.

Atrial fibrillation (AF) is the most common type. In AF, the atria beat chaotically and irregularly, leading to a rapid and erratic pulse. This can cause symptoms such as palpitations, shortness of breath, fatigue, and an increased risk of stroke due to blood clots forming in the quivering atria.

Ventricular fibrillation (VF) is a more life-threatening condition. In VF, the ventricles contract in a disorganized manner, resulting in a complete loss of effective pumping action. This leads to sudden cardiac arrest, as the heart can no longer deliver blood to the body. VF requires immediate medical intervention, typically defibrillation, to restore a normal heart rhythm.

Fibrillation can be caused by various factors, including underlying heart disease, high blood pressure, heart valve problems, thyroid disorders, and lifestyle factors such as excessive alcohol consumption or stress. Diagnosis often involves an electrocardiogram (ECG) to visualize the electrical activity of the heart. Treatment strategies vary depending on the type and severity of fibrillation and may include medications to control heart rate and rhythm, blood thinners to prevent clots, or procedures like cardioversion or catheter ablation.
