Abstract
Inappropriate sinus tachycardia (IST) is a chronic non-paroxysmal tachycardia arising from the sinus node, and is characterized by a sinus rate that is excessive with respect to the level of physical or psychological stress. Apart from early contributions given by Codvelle and Boucher [1] in 1939 and by Wising [2] in 1941, the first clinical report dedicated to this particular arrhythmia was published in 1979 by Bauernfeind et al. [3]. Although the concept of IST is obvious, there is no agreement on the quantitative criteria required for the diagnosis. This has resulted in substantial differences between published series of patients: for example all Bauernfeind’s patients had resting sinus rate > 100 [3], whereas 5 out of 6 patients reported by Morillo et al. [4] had normal resting heart rate even though reflecting an exaggerated rate response to physical activity.
