Overview

Supraventricular tachycardia is a collective term used to describe all the tachycardias originating from the SA node, atrium and AV node. Therefore, the causes depend on the source of the pathology, and they are as follows:

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.

Combined List of Causes in Alphabetical Order

Causes Based on Pathophysiologic Origin

SVTs from a Sinoatrial Source

Inappropriate Sinus Tachycardia

The cause of inappropriate sinus tachycardia is unknown. It is a diagnosis of exclusion after all the specific physiological and psychological triggers of sinus tachycardia have been excluded. The diagnosis of IST is based on the presence of a persistent and recurrent sinus tachycardia on EKG that is otherwise unexplainable.

Sinus Tachycardia

Sinoatrial Nodal Reentry Tachycardia
