Supraventrikulaarsest
Supraventrikulaarsest, also known as supraventricular tachycardia (SVT), is a type of abnormal heart rhythm that originates above the ventricles, specifically in the atria or atrioventricular node. It is characterized by a heart rate that is typically between 150 and 250 beats per minute, although it can be faster or slower. SVT can cause symptoms such as palpitations, dizziness, shortness of breath, and chest discomfort. The condition can be benign and self-limiting, but it can also be a sign of an underlying heart condition or other medical issues.
SVT can be classified into several types based on the specific mechanism of the abnormal rhythm. The
1. Atrial tachycardia: This occurs when the atria beat rapidly, but the ventricles beat normally.
2. Atrial flutter: This is characterized by a rapid, regular rhythm originating from the atria, with a
3. Atrial fibrillation: This is a chaotic and irregular rhythm originating from the atria, with no fixed
The diagnosis of SVT typically involves an electrocardiogram (ECG) to identify the specific type and mechanism
