supraventrikulaarselt
Supraventrikulaarselt is a term used in medicine, specifically in cardiology, to describe heart rhythms that originate above the ventricles of the heart. These rhythms are often referred to as supraventricular tachycardias (SVT), which are characterized by a rapid heart rate originating from the atria or the atrioventricular (AV) node. The electrical impulses that trigger these fast heartbeats begin in the upper chambers of the heart, either the atria or the AV junction, before they reach the ventricles, the lower chambers. This distinguishes them from ventricular tachycardias, which originate within the ventricles themselves.
Common types of supraventricular arrhythmias include atrial fibrillation, atrial flutter, and AV nodal reentrant tachycardia. Symptoms
