Supraventrikulaarsele

Supraventrikulaarsele is a type of abnormal heart rhythm that originates above the ventricles, the lower chambers of the heart. It is characterized by a rapid heart rate, typically exceeding 100 beats per minute, and is often associated with palpitations, dizziness, and shortness of breath. The most common types of supraventrikulaarsele include atrial fibrillation, atrial flutter, and supraventrikulaar tachycardia.

Atrial fibrillation is the most common type of supraventrikulaarsele, affecting approximately 2-3% of the adult population. It occurs when the electrical impulses in the atria, the upper chambers of the heart, become disorganized and chaotic, leading to a rapid and irregular heart rate. Atrial flutter is another type of supraventrikulaarsele that occurs when the electrical impulses in the atria form a rapid, regular circuit, resulting in a heart rate of 250-350 beats per minute. Supraventrikulaar tachycardia is a type of supraventrikulaarsele that occurs when the electrical impulses in the atria are abnormally fast, leading to a heart rate of 150-250 beats per minute.

Supraventrikulaarsele can be caused by a variety of factors, including heart disease, high blood pressure, thyroid problems, and certain medications. It can also be a symptom of an underlying medical condition, such as heart failure or coronary artery disease. In some cases, supraventrikulaarsele may occur without any identifiable cause.

The treatment of supraventrikulaarsele depends on the underlying cause and the severity of the symptoms. In many cases, lifestyle modifications, such as regular exercise, a healthy diet, and stress reduction, can help manage the condition. Medications, such as beta-blockers, calcium channel blockers, and antiarrhythmic drugs, may also be prescribed to control the heart rate and prevent complications. In some cases, electrical cardioversion or catheter ablation may be necessary to restore a normal heart rhythm.
