EMEDU ECG Supraventricular Tachycardia

Supraventricular Tachycardia

Supraventricular Tachycardia (nos)

All tachycardias in which the site of origin and the tachycardia pathway are not confined to the ventricle. In adults most SVT is due to atrioventricular nodal reentrant tachycardia AVNRT

SVT may Include:

Atrial Tachyarrhythmias	Atrioventricular Tachyarrhythmias
Sinus tachycardia Inappropriate sinus tachycardia (IST) Sinus nodal reentrant tachycardia (SNRT) Atrial tachycardia Multifocal atrial tachycardia (MAT) Atrial flutter Atrial fibrillation (AF) Ashman's Phenomenon	Atrioventricular nodal reentrant tachycardia (AVNRT) Atrioventricular reentrant tachycardia (AVRT) Junctional ectopic tachycardia (JET) Nonparoxysmal junctional tachycardia (NPJT)

ST segment changes may occur during SVT without coronary disease being present.
