supraventrikulaar

Supraventrikulaar refers to a condition or structure that is located above the ventricles, which are the lower chambers of the heart. The term is often used in medical contexts to describe abnormalities or procedures related to the upper parts of the heart. For example, supraventrikulaar tachycardia (SVT) is a type of abnormal heart rhythm that originates above the ventricles, typically in the atria or atrioventricular node. This condition can cause a rapid heart rate and may require medical intervention to restore normal heart rhythm.

In a surgical context, supraventrikulaar refers to the upper part of the heart that is accessed during certain procedures. For instance, in a supraventrikulaar tachycardia ablation, a catheter is guided through the veins to the heart, and a small lesion is created to disrupt the abnormal electrical pathway responsible for the rapid heart rate.

The supraventrikulaar approach is also used in certain cardiac surgeries, such as the Maze procedure, which is a surgical treatment for atrial fibrillation. This procedure involves creating multiple lesions in the atria to disrupt the abnormal electrical pathways and restore normal heart rhythm.

In summary, supraventrikulaar refers to a condition or structure located above the ventricles of the heart. It is used to describe abnormal heart rhythms, medical procedures, and surgical approaches related to the upper parts of the heart.
