Inappropriate Sinus Tachycardia (IST) is a clinical syndrome characterized by a sinus heart rate inexplicably higher than one hundred beats per minute at rest that are associated with symptoms like palpitations, dyspnea or dizziness in the absence of primary causes of tachycardia.

If it is due to anxiety, if it is due to low oxygen level, if it is due to some level of inflammation is still going on, if it read the underlying cause these things will settle down. But if somebody has inappropriate sinus tachycardia then they have to take treatment.
