Inappropriate sinus tachycardia causes
Introduction
Overview
Overview
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.
