Treatment for Inappropriate Sinus Tachycardia.

Inappropriate Sinus Tachycardia (IST) is a chronic medical condition with a wide variety of clinical presentations making it, sometimes, very insidious at the time of the diagnosis. Several therapeutic options, including, pharmacotherapy, cardiac rehabilitation, and modification or ablation of the sinus node, have been proposed for the management of IST, but because of the complexity and lack of understanding of pathophysiology, it can be difficult to manage, despite the numerous treatment options currently available. The purpose of this review is to analyze the treatment for IST, focusing on the role of newer therapy and the potential benefits in the management of this cardiac rhythm disturbance.
